CSIF Balanced (Note: Formerly known as CSIF Managed Growth)

Advisor                              Calvert Asset Management Company, Inc.
Subadvisors:                                 Brown Capital Management, Inc.
                                               NCM Capital Management, Inc.

Objective
CSIF Balanced seeks to achieve a competitive total return through an actively
managed portfolio of stocks, bonds and money market instruments which offer
income and capital growth opportunity and which satisfy the investment and
social criteria.

(Note: This objective is subject to shareholder approval expected at a
shareholder meeting in late February 1999. Unless and until shareholders
approve the new objective, the current objective for CSIF Balanced shall
continue in effect, which is CSIF Balanced "seeks to achieve a total return
above the rate of inflation, through an actively managed, diversified
portfolio of common and preferred stocks, bonds and money market instruments
which offer income and capital growth opportunity and which satisfy the
investment and social criteria.")

Principal investment strategies
The Fund typically invests about 60% of its assets in stocks and 40% in bonds
or other fixed-income investments. Stock investments are primarily common
stock in large-cap companies, while the fixed-income investments are primarily
a wide variety of investment grade bonds.

CSIF Balanced invests in a combination of stocks, bonds and money market
instruments in an attempt to provide a complete investment portfolio in a
single product. The Advisor rebalances the Fund quarterly to adjust for
changes in market value. The Fund is a large-cap, growth-oriented U.S.
domestic portfolio, although it may have other investments, including some
foreign securities and some mid-cap stocks. For the equity portion, the Fund
seeks companies with better than average expected growth rates at lower than
average valuations. The fixed-income portion reflects an active trading
strategy, seeking total return.

Equity investments are selected by the two Subadvisors, while the Advisor
manages the fixed-income assets and determines the overall mix for the Fund
depending upon its view of market conditions and economic outlook.

- --------------------------------------------------------------------------------
PRINCIPAL RISKS
You could lose money on your investment in the Fund, or the Fund could
underperform for any of the following reasons:

      The stock or bond market goes down
      The individual stocks and bonds in the Fund do not perform as well as
     expected
      For the fixed-income portion of the Fund, the Advisor's forecast as to
     interest rates is not correct
      For the foreign securities held in the Fund, if foreign currency values
     go down versus the U.S. dollar
      The Advisor's allocation among different sectors of the stock and bond
     markets does not perform as well as expected

An investment in the Fund is not a bank deposit and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other
government agency.
- --------------------------------------------------------------------------------

<PAGE>

The Fund invests with the philosophy that long-term rewards to investors will
come from those organizations whose products, services, and methods enhance
the human condition and the traditional American values of individual
initiative, equality of opportunity and cooperative effort. Investments are
selected on the basis of their ability to contribute to the dual objectives of
financial soundness and social criteria. See "Investment Selection Process."


CSIF Balanced Performance

The bar chart and table below show the Fund's annual returns and its long-term
performance. The chart shows how the performance of the Class A shares has
varied from year to year. The table compares the Fund's performance over time
to that of the Standard & Poor's 500 Index and the Lehman Aggregate Bond
Index, a widely recognized, unmanaged index of common stock and bonds prices,
respectively. It also shows the Fund's returns compared to the Lipper Balanced
Funds Index, a composite index of the annual return of mutual funds that have
an investment goal similar to that of the Fund. The Fund's past performance
does not necessarily indicate how the Fund will perform in the future.

The return for the Fund's other classes of shares offered by this prospectus
will differ from the Class A returns shown in the bar chart, depending upon
the expenses of that Class. The bar chart does not reflect any sales charge
that you may be required to pay upon purchase or redemption of the Fund's
shares. Any sales charge will reduce your return. The average total return
table shows returns with the maximum sales charge deducted. No sales charge
has been applied to the index used for comparison in the table.

CSIF Managed Index

Advisor                              Calvert Asset Management Company, Inc.
Subadvisor:                                    State Street Global Advisors

Objective
CSIF Managed Index seeks a total return after expenses which exceeds over time
the total return of the Russell 1000 Index. It seeks to obtain this objective
while maintaining risk characteristics similar to those of the Russell 1000
Index and through investments in stocks that meet the Fund's investment and
social criteria. This objective may be changed by the Fund's Board of
Trustees/Directors without shareholder approval.

Principal investment strategies
The Fund invests in stocks that meet the social criteria and creates a
portfolio whose characteristics closely resemble the characteristics of the
Russell 1000 Index, while emphasizing the stocks which it believes offer the
greatest potential of return.

CSIF Managed Index follows an enhanced index management strategy. Instead of
passively holding a representative basket of securities designed to match the
Russell 1000 Index, the Subadvisor actively uses a proprietary analytical
model to attempt to enhance the Fund's performance, relative to the Index. The
Fund may purchase stocks not in the Russell 1000 Index, but at least 65% of
the Fund's total assets will be invested in stocks that are in the Index. Any
investments not in the Index will meet the Fund's social screening criteria
and be selected to closely mirror the Index's risk/return characteristics. The
Subadvisor rebalances the Fund quarterly to maintain its relative exposure to
the Index.

The first step of the investment strategy is to identify those stocks in the
Russell 1000 Index which meet the Fund's social screening criteria. From this
list of stocks, the Subadvisor chooses stocks that closely mirror the Index in
terms of various factors such as industry weightings, capitalization, and
yield. Even though certain industries may be eliminated from the Fund by the
screens, the factor model permits mathematical substitutes which the
Subadvisor expects to mimic the return characteristics of the missing
industries and stocks.

- --------------------------------------------------------------------------------
PRINCIPAL RISKS
You could lose money on your investment in the Fund, or the Fund could
underperform the stock market for any of the following reasons:

      The stock market or the Russell 1000 Index goes down
      The individual stocks in the Fund or the index modeling portfolio do not
     perform as well as expected
      An index fund has operating expenses; a market index does not. The Fund
     - while expected to track its target index as closely as possible while
     satisfying its investment and social criteria - will not be able to match
     the performance of the index exactly

An investment in the Fund is not a bank deposit and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other
government agency. The Fund is not sponsored, sold, promoted or endorsed by
the Frank Russell Company.
- --------------------------------------------------------------------------------

<PAGE>

The final step in the process is to apply the Subadvisor's proprietary
valuation method which attempts to identify the stocks which have the greatest
potential for superior performance. Each security identified for potential
investment is ranked according to two separate measures: value and momentum of
market sentiment. These two measures combine to create a single composite
score of each stock's attractiveness. The Fund is constructed from securities
that meet its social criteria, weighted through a mathematical process that
seeks to reduce risk vis-a-vis the Russell 1000 Index. The Subadvisor expects
to hold between 100 and 150 stocks.

The Russell 1000 Index measures the performance of the 1,000 largest U.S.
companies based on total market capitalization. The Index is adjusted, or
reconstituted, annually. As of the latest reconstitution, the average market
capitalization of the Russell 1000 was approximately $7.6 billion.

Tracking the Index
The Subadvisor expects a tracking error over time of no more than 2.5%,
although there can be no guarantee such results will be achieved. The Fund's
ability to track the Index will be monitored by analyzing returns to ensure
that the returns are reasonably consistent with Index returns. Any deviations
of realized returns from the Index which are in excess of those expected will
be analyzed for sources of variance. Where variations are deemed to be
systematic or associated with a particular feature of the investment process,
the constraints on the Fund associated with that factor may be adjusted to
ensure a higher degree of correlation to the Index.

The Fund invests with the philosophy that long-term rewards to investors will
come from those organizations whose products, services, and methods enhance
the human condition and the traditional American values of individual
initiative, equality of opportunity and cooperative effort. Investments are
selected on the basis of their ability to contribute to the dual objectives of
financial soundness and social criteria. See "Investment Selection Process."

Objective
CSIF Equity seeks growth of capital through investment in stocks of issuers in
industries believed to offer opportunities for potential capital appreciation
and which meet the Fund's investment and social criteria.

Principal investment strategies
The Fund invests primarily in the common stocks of large-cap companies,
having, on average, market capitalization of at least $1 billion. Investment
returns will be mostly from changes in the price of the Fund's holdings
(capital appreciation).

The Subadvisor looks for growing companies with a history of steady earnings
growth. Companies are selected based on the Subadvisor's opinion that the
company has the ability to sustain growth through growing profitability and
that the stock is favorably priced with respect to those growth expectations.

The Fund invests with the philosophy that long-term rewards to investors will
come from those organizations whose products, services, and methods enhance
the human condition and the traditional American values of individual
initiative, equality of opportunity and cooperative effort. Investments are
selected on the basis of their ability to contribute to the dual objectives of

Calvert Capital Accumulation

Advisor                              Calvert Asset Management Company, Inc.
Subadvisor:                                  Brown Capital Management, Inc.

Objective
Capital Accumulation seeks to provide long-term capital appreciation by
investing primarily in mid-cap stocks that meet the Fund's investment and
social criteria. This objective may be changed by the Fund's Board of
Trustees/Directors without shareholder approval.

Principal investment strategies
Investments are primarily in the common stocks of mid-size companies. Returns
in the Fund will be mostly from the changes in the price of the Fund's
holdings (capital appreciation.)

The Fund currently defines mid-cap companies as those within the range of
market capitalizations of the S & P's Mid-cap 400 Index. Most companies in the
Index have a capitalization of $500 million to $10 billion. Stocks chosen for
the Fund combine growth and value characteristics or offer the opportunity to
buy growth at a reasonable price.

The Subadvisor favors companies which have an above market average prospective
growth rate, but sell at below market average valuations. The Subadvisor
evaluates each stock in terms of its growth potential, the return for risk
free investments, and the risk and reward potential for the company to
determine a reasonable price for the stock.

The Fund invests with the philosophy that long-term rewards to investors will
come from those organizations whose products, services, and methods enhance
the human condition and the traditional American values of individual
initiative, equality of opportunity and cooperative effort. Investments are
selected on the basis of their ability to contribute to the dual objectives of
financial soundness and social criteria. See "Investment Selection Process."

- --------------------------------------------------------------------------------
PRINCIPAL RISKS
You could lose money on your investment in the Fund, or the Fund could
underperform for any of the following reasons:

      The stock market goes down
      The individual stocks in the Fund do not perform as well as expected
      The Fund is non-diversified. Compared to other funds, the Fund may
     invest more of its assets in a smaller number of companies. Gains or
     losses on a single stock may have greater impact on the Fund.

An investment in the Fund is not a bank deposit and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other
government agency.

Calvert World Values
International Equity Fund

Advisor                              Calvert Asset Management Company, Inc.
Subadvisor:                            Murray Johnstone International, Ltd.

Objective
CWVF International Equity seeks to provide a high total return consistent with
reasonable risk by investing primarily in a globally diversified portfolio of
stocks that meet the Fund's investment and social criteria.

Principal investment strategies
The Fund invests primarily in the common stocks of mid- to large-cap companies
using a value approach. The Fund identifies those countries with markets and
economies that it believes currently provide the most favorable climate for
investing. The Subadvisor selects countries based on a "20 questions" model
which uses macro-and micro-economic inputs to rank the attractiveness of
markets in various countries. Within each country, the Subadvisor uses
valuation techniques that have been shown to best determine value within that
market. In some countries, the valuation process may favor the comparison of
price-to-cash-flow while in other countries, price-to-sales or price-to-book
may be more useful in determining which stocks are undervalued.

The Fund invests primarily in more developed economies and markets. No more
than 5% of Fund assets are invested in the U.S. (excluding High Social Impact
and Special Equities investments).

The Fund invests with the philosophy that long-term rewards to investors will
come from those organizations whose products, services, and methods enhance
the human condition and the traditional American values of individual
initiative, equality of opportunity and cooperative effort. Investments are
selected on the basis of their ability to contribute to the dual objectives of
financial soundness and social criteria. See "Investment Selection Process."

- --------------------------------------------------------------------------------
PRINCIPAL RISKS
You could lose money on your investment in the Fund, or the Fund could
underperform for any of the following reasons:

      The stock markets go down (including those outside the U.S.)
      The individual stocks in the Fund do not perform as well as expected
      Foreign currency values go down versus the U.S. dollar

An investment in the Fund is not a bank deposit and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other
government agency.

Calvert New Vision Small Cap

Advisor                              Calvert Asset Management Company, Inc.
Subadvisor:                                     Awad Asset Management, Inc.

Objective
New Vision Small Cap seeks to provide long-term capital appreciation by
investing primarily in small-cap stocks that meet the Fund's investment and
social criteria. This objective may be changed by the Fund's Board of
Trustees/Directors without shareholder approval.

Principal Investment Strategies
At least 65% of the Fund's assets will be invested in the common stocks of
small-cap companies. Returns in the Fund will be mostly from the changes in
the price of the Fund's holdings (capital appreciation).

The Fund currently defines small-cap companies as those with market
capitalization of $1 billion or less at the time the Fund initially invests.

The Fund invests with the philosophy that long-term rewards to investors will
come from those organizations whose products, services, and methods enhance
the human condition and the traditional American values of individual
initiative, equality of opportunity and cooperative effort. Investments are
selected on the basis of their ability to contribute to the dual objectives of
financial soundness and social criteria. See "Investment Selection Process."

- --------------------------------------------------------------------------------
PRINCIPAL RISKS
You could lose money on your investment in the Fund, or the Fund could
underperform for any of the following reasons:

      The stock market goes down
      The individual stocks in the Fund do not perform as well as expected
      Prices of small-cap stocks may respond to market activity differently
     than larger more established companies

An investment in the Fund is not a bank deposit and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other
government agency.

New Vision Small Cap Performance

The bar chart and table below show the Fund's annual returns and its long-term
performance. The chart shows how the performance of the Class A shares has
varied from year to year. The table compares the Fund's performance over time
to that of the Russell 2000 Index. This is a widely recognized, unmanaged
index of common stock prices. It also shows the Fund's returns compared to the
Lipper Small-Cap Funds Index, a composite index of the annual return of mutual
funds that have an investment goal similar to that of the Fund. The Fund's
past performance does not necessarily indicate how the Fund will perform in
the future.

The return for the Fund's other Classes of shares offered by this prospectus
will differ from the Class A returns shown in the bar chart, depending upon
the expenses of that Class. The bar chart does not reflect any sales charge
that you may be required to pay upon purchase or redemption of the Fund's
shares. Any sales charge will reduce your return. The average total return
table shows returns with the maximum sales charge deducted. No sales charge
has been applied to the index used for comparison in the table.

CSIF Bond

Advisor:                             Calvert Asset Management Company, Inc.

Objective
CSIF Bond seeks to provide as high a level of current income as is consistent
with prudent investment risk and preservation of capital through investment in
bonds and other straight debt securities meeting the Fund's investment and
social criteria.

Principal investment strategies
The Fund uses an active strategy, seeking relative value to earn incremental
income. The Fund typically invests at least 65% of its assets in investment
grade debt securities.

The Fund invests with the philosophy that long-term rewards to investors will
come from those organizations whose products, services, and methods enhance
the human condition and the traditional American values of individual
initiative, equality of opportunity and cooperative effort. Investments are
selected on the basis of their ability to contribute to the dual objectives of
financial soundness and social criteria. See "Investment Selection Process."

- --------------------------------------------------------------------------------
PRINCIPAL RISKS
You could lose money on your investment in the Fund, or the Fund could
underperform, most likely for any of the following reasons:

      The bond market goes down
      The individual bonds in the Fund do not perform as well as expected
      The Advisor's forecast as to interest rates is not correct
      The Advisor's allocation among different sectors of the bond market does
     not perform as well as expected
      The Fund is non-diversified. Compared to other funds, the Fund may
     invest more of its assets in a smaller number of companies. Gains or
     losses on a single bond may have greater impact on the Fund. (The Fund's
     non-diversified status is subject to shareholder approval, expected at a
     shareholder meeting in late February 1999. Unless and until the
     shareholders approve the change, the fund will be diversified.)

An investment in the Fund is not a bank deposit and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other
government agency.

CSIF Money Market

Advisor:                             Calvert Asset Management Company, Inc.

Objective
CSIF Money Market seeks to provide the highest level of current income,
consistent with liquidity, safety and security of capital, through investment
in money market instruments meeting the Fund's investment and social criteria

Principal investment strategies
The Fund invests in high quality, money market instruments, such as commercial
paper, variable rate demand notes, corporate, agency and taxable municipal
obligations. All investments must comply with the SEC money market fund
requirements.

The Fund invests with the philosophy that long-term rewards to investors will
come from those organizations whose products, services, and methods enhance
the human condition and the traditional American values of individual
initiative, equality of opportunity and cooperative effort. Investments are
selected on the basis of their ability to contribute to the dual objectives of
financial soundness and social criteria. See "Investment Selection Process."

- --------------------------------------------------------------------------------
PRINCIPAL RISKS
The Fund's yield will change in response to market interest rates. In general,
as market rates go up so will the Fund's yield, and vice versa. Although the
Fund tries to keep the value of its shares constant at $1.00 per share,
extreme changes in market rates, and or sudden credit deterioration of a
holding could cause the value to decrease. The Fund limits the amount it
invests in any one issuer to try to lessen its exposure.

An investment in the Fund is not a bank deposit and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other
government agency. Although the Fund seeks to preserve the value of your
investment at $1.00 per share, it is still possible to lose money by investing
in the Fund.

Explanation of Fees and Expenses Table

1 Expenses are based on estimates for the current fiscal year.
2 Purchases of Class A shares for accounts with $1 million or more are not
subject to front-end sales charges, but may be subject to a 1.0% contingent
deferred sales charge on shares redeemed within 1 year of purchase. (See "How
to Buy Shares - Class A)
3 For each account with a balance of less than $5000 (less than $1000 for
IRAs), the Fund charges a monthly account maintenance fee of $1.00.
4 For each account with a balance of less than $1000, the Fund charges a
monthly account maintenance fee of $3.00.
5 CAMCO has agreed to waive fees and or reimburse expenses (net of any expense
offset arrangements) for certain of the Funds through December 31, 1999: CSIF
Money Market, CSIF Balanced (Class B and I), CSIF Equity (Class B and I) CSIF
Bond (Class B, C, and I), CSIF Managed Index (Class A, B, C, and I), CWVF
International Equity (Class B and I) Capital Accumulation (Class B and I), and
New Vision (Class B and I). The contractual expense cap is shown as "Net
Expenses", this is the maximum amount that may be charged to the Funds for
this period.
6 A contingent deferred sales charge is imposed on the proceeds of Class B
shares redeemed within 6 years, subject to certain exceptions. The charge is a
percentage of net asset value at the time of purchase or redemption, whichever
is less, and declines from 5% in the first year that shares are held, to 4% in
the second and third year, 3% in the fourth year, 2% in the fifth year, and 1%
in the sixth year. There is no charge on redemptions of Class B shares held
for more than six years. See "Calculation of Contingent Deferred Sales Charge"
7 A contingent deferred sales charge is imposed on the proceeds of Class B
shares of CSIF Bond redeemed within 4 years, subject to certain exceptions.
The charge is a percentage of net asset value at the time of purchase or
redemption, whichever is less, and declines from 4% in the first year that
shares are held, to 3% in the second, 2% in the third year, and 1% in the
fourth year. There is no charge on redemptions of Class B shares held for more
than four years. See "Calculation of Contingent Deferred Sales Charge"
8 A contingent deferred sales charge is imposed on the proceeds of Class C
shares redeemed within one year. The charge is a percentage of net asset value
at the time of purchase or redemption, whichever is less. See "Calculation of
Contingent Deferred Sales Charge"
9 The Management fees for CSIF Balanced, CSIF Equity, and Calvert Capital
Accumulation have been restated to reflect changes expected to be approved by
shareholders in early 1999. If shareholders do not approve the changes to the
fees, the Management

<PAGE>

fees and Total annual Fund operating expenses, and Net Expenses, if
applicable, would be 0.07% lower for CSIF Balanced, 0.14% lower for CSIF
Equity, and 0.01% lower for Capital Accumulation. See "About Calvert Group -
Advisory Fees".
10 Expenses for New Vision Small Cap have been restated to reflect expenses
expected to be incurred in 1999.

Annual Fund Operating Expenses
Expenses are based on expenses for the Fund's most recent fiscal year, unless
otherwise indicated. Management fees include the Subadvisory fees paid by the
Advisor ("CAMCO") to the Subadvisors, and, if applicable, the administrative
fee paid by the Fund to Calvert Administrative Services Company, an affiliate
of CAMCO.

Each Fund's Rule 12b-1 fees include an asset-based sales charge. Thus,
long-term shareholders in a Fund may pay more in total sales charges than the
economic equivalent of the maximum front-end sales charge permitted by rules
of the National Association of Securities Dealers, Inc. (the "NASD").

Example
This example is intended to help you compare the cost of investing in a Fund
with the cost of investing in other mutual funds. The example assumes that:
          You invest $10,000 in the Fund for the time periods indicated;
          Your investment has a 5% return each year; and
          The Fund's operating expenses remain the same.

Although your actual costs may be higher or lower, under these assumptions
your costs would be:

PRINCIPAL INVESTMENT PRACTICES AND RISKS

The most concise description of each Fund's principal investment strategies
and associated risks is under the risk-return summary for each Fund. The Funds
are also permitted to invest in certain other investments and to use certain
investment techniques that have higher risks associated with them. On the
following pages are brief descriptions of the investments and techniques,
summarized in the risk-return summary along with certain additional investment
techniques and their risks.

For each of the investment practices listed, the table below shows each Fund's
limitations as a percentage of its assets and the principal types of risk
involved. (See the pages following the table for a description of the types of
risks). Numbers in this table show maximum allowable amount only; for actual
usage, consult the Fund's annual/semi-annual reports.

<PAGE>

The Funds have additional investment policies and restrictions that are
not principal to their investment strategies (for example, repurchase
agreements, real estate investment trusts, borrowing, pledging, and
reverse repurchase agreements, securities lending, when-issued securities
and short sales.) These policies and restrictions are discussed in the SAI.

Types of Investment Risk

Correlation risk
This occurs when a Fund "hedges"- uses one investment to offset the Fund's
position in another. If the two investments do not behave in relation to one
another the way Fund managers expect them to, then unexpected or undesired
results may occur. For example, a hedge may eliminate or reduce gains as well
as offset losses.

Credit risk
The risk that the issuer of a security or the counterparty to an investment
contract may default or become unable to pay its obligations when due.

Currency risk
Currency risk occurs when a Fund buys, sells or holds a security denominated
in foreign currency. Foreign currencies "float" in value against the U.S.
dollar. Adverse changes in foreign currency values can cause investment losses
when a Fund's investments are converted to U.S. dollars.

Extension risk
The risk that an unexpected rise in interest rates will extend the life of a
mortgage-backed security beyond the expected prepayment time, typically
reducing the security's value.

Information risk
The risk that information about a security or issuer or the market might not
be available, complete, accurate or comparable.

Interest rate risk
The risk that changes in interest rates will adversely affect the value of an
investor's securities. When interest rates rise, the value of fixed-income
securities will generally fall. Conversely, a drop in interest rates will
generally cause an increase in the value of fixed-income securities.
Longer-term securities and zero coupon/"stripped" coupon securities ("strips")
are subject to greater interest rate risk.

Leverage risk
The risk that occurs in some securities or techniques which tend to magnify
the effect of small changes in an index or a market. This can result in a loss
that exceeds the amount actually invested.

<PAGE>

Liquidity risk
The risk that occurs when investments cannot be readily sold. A Fund may have
to accept a less-than-desirable price to complete the sale of an illiquid
security or may not be able to sell it at all.

Management risk
This risk exists in all mutual funds and means that a Fund's portfolio
management practices might not work to achieve their desired result.

Market risk
The risk that exists in all mutual funds and means the risk that securities
prices in a market, a sector or an industry will fluctuate, and that such
movements might reduce an investment's value.

Opportunity risk
The risk of missing out on an investment opportunity because the assets needed
to take advantage of it are committed to less advantageous investments or
strategies.

Political risk
The risk that may occur with foreign investments, and means that the value of
an investment may be adversely affected by nationalization, taxation, war,
government instability or other economic or political actions or factors.

Prepayment risk
The risk that unanticipated prepayments may occur, reducing the value of a
mortgage-backed security. The Fund must then reinvest those assets at the
current, market rate which may be lower.

Transaction risk
The risk that a Fund may be delayed or unable to settle a transaction or that
commissions and settlement expenses may be higher than usual.

INVESTMENT SELECTION PROCESS
Investments are selected on the basis of their ability to contribute to the
dual objectives of financial soundness and social criteria.

Potential investments for a Fund are first selected for financial soundness
and then evaluated according to that Fund's social criteria. To the greatest
extent possible, Calvert Social Investment Fund (CSIF) and Calvert World
Values International Equity Fund (CWVF) seek to invest in companies that
exhibit positive accomplishments with respect to

<PAGE>

one or more of the social criteria. Investments for all Funds must meet the
minimum standards for all its financial and social criteria.

Although each Fund's social criteria tend to limit the availability of
investment opportunities more than is customary with other investment
companies, CAMCO and the Subadvisors of the Funds believe there are sufficient
investment opportunities to permit full investment among issuers which satisfy
each Fund's investment and social objectives.

The selection of an investment by a Fund does not constitute endorsement or
validation by that Fund, nor does the exclusion of an investment necessarily
reflect failure to satisfy the Fund's social criteria. Investors are invited
to send a brief description of companies they believe might be suitable for
investment.

Socially Responsible Investment Criteria

The Funds invest in accordance with the philosophy that long-term rewards to
investors will come from those organizations whose products, services, and
methods enhance the human condition and the traditional American values of
individual initiative, equality of opportunity and cooperative effort. In
addition, we believe that there are long-term benefits in an investment
philosophy that demonstrates concern for the environment, labor relations,
human rights and community relations. Those enterprises that exhibit a social
awareness in these issues should be better prepared to meet future societal
needs. By responding to social concerns, these enterprises should not only
avoid the liability that may be incurred when a product or service is
determined to have a negative social impact or has outlived its usefulness,
but also be better positioned to develop opportunities to make a profitable
contribution to society. These enterprises should be ready to respond to
external demands and ensure that over the longer term they will be viable to
seek to provide a positive return to both investors and society as a whole.


Each Fund has developed social investment criteria, detailed below. These
criteria represent standards of behavior which few, if any, organizations
totally satisfy. As a matter of practice, evaluation of a particular
organization in the context of these criteria will involve subjective judgment
by CAMCO and the Subadvisors. All social criteria may be changed by the Board
of Trustees/Directors without shareholder approval.

Calvert Social Investment Fund
CSIF seeks to invest in companies that:

      Deliver safe products and services in ways that sustain our natural
     environment. For example, CSIF looks for companies that produce energy
     from renewable resources, while avoiding consistent polluters.


      Manage with participation throughout the organization in defining and
     achieving objectives. For example, CSIF looks for companies that offer
     employee stock ownership or profit-sharing plans.

      Negotiate fairly with their workers, provide an environment supportive
     of their wellness, do not discriminate on the basis of race, gender,
     religion, age, disability, ethnic origin, or sexual orientation, do not
     consistently violate regulations of the EEOC, and provide opportunities
     for women, disadvantaged minorities, and others for whom equal
     opportunities have often been denied. For example, CSIF considers both
     unionized and non-union firms with good labor relations.

      Foster awareness of a commitment to human goals, such as creativity,
     productivity, self-respect and responsibility, within the organization
     and the world, and continually recreates a context within which these
     goals can be realized. For example, CSIF looks for companies with an
     above average commitment to community affairs and charitable giving.

CSIF will not invest in companies that the Advisor determines to be
significantly engaged in:

      Production, or the manufacture of equipment, to produce nuclear energy

      Business activities in support of repressive regimes

      Manufacture of weapon systems

      Manufacture of alcoholic beverages or tobacco products

      Operation of gambling casinos

With respect to U.S. government securities, CSIF invests primarily in debt
obligations issued or guaranteed by agencies or instrumentalities of the U.S.
Government whose purposes further or are compatible with CSIF's social
criteria, such as obligations of the Student Loan Marketing Association,
rather than general obligations of the U.S. Government, such as Treasury
securities.

<PAGE>

Calvert International Equity Fund

The spirit of Calvert World Values International Equity Fund's social criteria
is similar to CSIF, but the application of the social analysis is
significantly different. International investing brings unique challenges in
terms of corporate disclosure, regulatory structures, environmental standards,
and differing national and cultural priorities. Due to these factors, the CWVF
social investment standards are less stringent than those of CSIF.

CWVF seeks to invest in companies that:

      Achieve excellence in environmental management. We select investments
     that take positive steps toward preserving and enhancing our natural
     environment through their operations and products. We avoid companies
     with poor environmental records.

      Have positive labor practices. We consider the International Labor
     Organization's basic conventions on worker rights as a guideline for our
     labor criteria. We seek to invest in companies that hire and promote
     women and ethnic minorities; respect the right to form unions; comply, at
     a minimum, with domestic hour and wage laws; and provide good health and
     safety standards. We avoid companies that demonstrate a pattern of
     engaging in forced, compulsory, or child labor.

CWVF avoids investing in companies that:

      Contribute to human rights abuses in other countries1

      Produce nuclear power or nuclear weapons, or have more than 10% of
     revenues derived from the production or sale of weapons systems

      Derive more than 10% of revenues from the production of alcohol or
     tobacco products, but actively seeks to invest in companies whose
     products or services improve the quality of or access to health care,
     including public health and preventative medicine

1 CWVF may invest in companies that operate in countries with poor human
rights records if we believe the companies are making a positive contribution.

<PAGE>

Calvert Capital Accumulation Fund
Calvert New Vision Small Cap Fund

The Funds carefully review company policies and behavior regarding social
issues important to quality of life such as:

      environment
      employee relations
      product criteria
      weapons systems
      nuclear energy
      human rights

Both Funds will avoid investing in companies that have:

      Significant or historical patterns of violating environmental
     regulations, or otherwise have an egregious environmental record

      Significant or historical patterns of discrimination against employees
     on the basis of race, gender, religion, age, disability or sexual
     orientation, or that have major labor-management disputes

      Nuclear power plant operators and owners, or manufacturers of key
     components in the nuclear power process

      Significantly engaged in weapons production (including weapons systems
     contractors and major nuclear weapons systems contractors)

      Significantly involved in the manufacture of tobacco or alcohol products

      Products or offer services that, under proper use, are considered harmful

The Advisor will seek to review companies' overseas operations consistent with
the social criteria stated above.

While Capital Accumulation and New Vision may invest in companies that exhibit
positive social characteristics, they make no explicit claims to seek out
companies with such practices.

High Social Impact Investments - CSIF Balanced, Bond and Equity, Calvert World
Values International Equity, Capital Accumulation and New Vision Small Cap


High Social Impact Investments is a program that targets a percentage of the
Fund's assets (up to 1% for each of CSIF Balanced, CSIF Equity and CSIF Bond
and New Vision and up to 3% for each of CWVF International Equity and Capital
Accumulation) to directly support the growth of community-based organizations
for the purposes of promoting business creation, housing development, and
economic and social development of urban and rural communities. These types of
investments offer a rate of return below the then-prevailing market rate, and
are considered illiquid, unrated and below-investment grade. They also involve
a greater risk of default or price decline than investment grade securities.
However, they have a significant social return by making a tremendous
difference in our local communities. High Social Impact Investments are valued
under the direction and control of the Fund's Board.

The Funds have received an exemptive order to permit them to invest those
assets allocated for investment in high social impact investments through the
purchase of Community Investment Notes from the Calvert Social Investment
Foundation. The Calvert Social Investment Foundation is a non-profit
organization, legally distinct from Calvert Group, organized as a charitable
and educational foundation for the purpose of increasing public awareness and
knowledge of the concept of socially responsible investing. It has instituted
the Calvert Community Investments program to raise assets from individual and
institutional investors and then invest these assets directly in non-profit or
not-for-profit community development organizations and community development
banks that focus on low income housing, economic development and business
development in urban and rural communities.

Special Equities
CSIF Balanced and Calvert World Values International Equity

CSIF Balanced and CWVF International Equity each have a Special Equities
investment program that allows the Fund to promote especially promising
approaches to social goals through privately placed investments. The
investments are generally venture capital investments in small, untried
enterprises. The Special Equities Committee of each Fund identifies,
evaluates, and selects the Special Equities investments. Special Equities
involve a high degree of risk - they are subject to liquidity, information,
and if a debt investment, credit risk. Special Equities are valued under the
direction and control of the Fund's Board.

Advisory Fees

The following table shows the aggregate annual advisory fee paid to CAMCO by
each Fund for the most recent fiscal year as a percentage of that Fund's
average daily net assets .

Fund                                     Advisory Fee
CSIF Balanced                              0.62% 2, 5
CSIF Managed Index                         0.60% 3, 4
CSIF Equity                                0.56% 2, 5
CSIF Bond                                  0.55% 1, 2
CSIF Money Market                             0.50% 2
CWVF International Equity                     1.00% 2
Capital Accumulation                       0.79% 2, 5
New Vision Small Cap                          0.90% 2

1 CAMCO waived part of its advisory fee for CSIF Bond. The full contractual
rate CSIF Bond was obligated to pay CAMCO for fiscal year 1998 was 0.65%.

2 These advisory agreements are proposed to be changed by a vote of
shareholders in February 1999. If approved, the new advisory fee would be:
CSIF Balanced, 0.425%; CSIF Equity, 0.50%; CSIF Bond, 0.35%; CSIF Money
Market, 0.30%; CWVF International Equity, 0.75%; Capital Accumulation, 0.65%;
and New Vision Small Cap, 0.75%. The proposed lower advisory fee for each
Fund, when added to the proposed new administrative services fee, would equal
the current advisory fee (excluding the effect of any performance adjustment -
see note 5 below)

3 CSIF Managed Index has not had a full year of operations. Its advisory
agreement provides for a fee of 0.60% of the Portfolio's first $500 million of
average daily net assets and 0.55% of any such assets over $500 million.

4 CSIF Managed Index has a recapture provision under which CAMCO may elect to
recapture from the Fund in a later year any fees CAMCO waives or expenses it
assumes, subject to certain limitations.

5 CSIF Balanced has a performance adjustment which could cause the fee to be
as high as 0.85% or low as 0.55%, depending on its performance relative to the
relevant index (CAMCO: Lehman Aggregate Bond; NCM: Russell 3000; Brown: S&P
500). CSIF Equity has a performance adjustment which could cause the fee to be
as high as 0.90% or as low as 0.50% depending on its performance relative to
the S&P 500 Index. Capital Accumulation has a performance adjustment which
could cause the fee to be as high as 0.85% or as low as 0.75%, depending on
its performance relative to the S&P 400 Midcap Index. These performance
adjustments are proposed to be eliminated by a vote of shareholders in
February, 1999.

A Word About the Year 2000 (Y2K) and Our Computer Systems

Like other mutual funds, CAMCO and its service providers use computer systems
for all aspects of our business -- processing shareholder and fund
transactions, fund accounting, executing trades, and pricing securities just
to name a few. Many current software programs cannot distinguish between the
year 2000 and the year 1900. This can cause problems with retirement plan
distributions, dividend payment software, transaction software, and numerous
other areas that could impact the Funds. Calvert Group has been reviewing all
of its computer systems for Y2K compliance. Although, at this time, there can
be no assurance that there will be no negative impact on the Funds, the
Advisor, the underwriter, transfer agent and custodian have advised the Funds
that they have been actively working on any necessary changes to their
computer systems to prepare for Y2K and expect that their systems, and those
of their outside service providers, will be adapted in time for that event.

HOW TO BUY SHARES

Getting Started - Before You Open an Account
You have a few decisions to make before you open an account in a mutual fund.

First, decide which fund or funds best suits your needs and your goals.

Second, decide what kind of account you want to open. Calvert offers
individual, joint, trust, Uniform Gifts/Transfers to Minor Accounts,
Traditional, Education and Roth IRAs, Qualified Profit-Sharing and Money
Purchase Plans, SIMPLE IRAs, SEP-IRAs, 403(b)(7) accounts, and several other
types of accounts. Minimum investments are lower for the retirement plans.

Then decide which class of shares is best for you.

You should make this decision carefully, based on:
          the amount you wish to invest;
          the length of time you plan to keep the investment; and
          the Class expenses.

Choosing a Share Class

CSIF Money Market offers only one class of shares, which is sold without a
sales charge. The other Funds in this prospectus offer three different Classes
(Class A, B, or C). This chart shows the difference in the Classes and the
general types of investors who may be interested in each Class:

Class A: Front-End Sales    Class B: Deferred Sales   Class C: Deferred Sales
Charge                      Charge for 6 years (4     Charge for 1 year

Class A
If you choose Class A, you will pay a sales charge at the time of each
purchase. This table shows the charges both as a percentage of offering price
and as a percentage of the amount you invest. The term "offering price"
includes the front-end sales charge. If you invest more, the sales charge will
be lower. For example, if you invest more than $50,000, or if your cumulative
purchases or the value in your account is more than $50,000,4 then the sales
charge is reduced to 3.75%.

4 This is called "Rights of Accumulation." The sales charge is calculated by
taking into account not only the dollar amount of the new purchase of shares,
but also the higher of cost or current value of shares you have previously
purchased in Calvert Group Funds that impose sales charges. This automatically
applies to your account for each new purchase of Class A shares.

* Purchases of Class A shares at NAV for accounts with $1,000,000 or more are
subject to a one year CDSC of 1.00%. See the "Calculation of Contingent
Deferred Sales Charge and Waiver of Sales Charges."

<PAGE>

The Class A front-end sales charge may be waived for certain purchases or
investors, such as participants in certain group retirement plans or other
qualified groups and clients of registered investment advisers. For details on
these and other purchases that may qualify for a reduced sales charge, see
Exhibit A.

Class B
If you choose Class B, there is no front-end sales charge like Class A, but if
you sell the shares within the first 6 years (or 4 years for CSIF Bond), you
will have to pay a "contingent deferred" sales charge ("CDSC"). This means
that you do not have to pay the sales charge unless you sell your shares
within the first 6 years after purchase (or 4 years for CSIF Bond). Keep in
mind that the longer you hold the shares, the less you will have to pay in
deferred sales charges.

Calculation of Contingent Deferred Sales Charge and Waiver of Sales Charges
The CDSC will not be charged on shares you received as dividends or from
capital gains distributions or on any capital appreciation (gain in the value)
of shares that are sold.

Shares that are not subject to the CDSC will be redeemed first, followed by
shares you have held the longest. The CDSC is calculated by determining the
share value at both the time of purchase and redemption and then multiplying
whichever value is less by the percentage that applies as shown above. For
example, if you invested $5,000 in CSIF Equity Class B shares three years ago,
and it is now worth $5,750, the CDSC will be calculated by taking the lesser
of the two values ($5,000), and multiplying it by 4%, for a CDSC of $200. If
you choose to sell only part of your shares, the capital appreciation for
those shares only is included in the calculation, rather than the capital
appreciation for the entire account.

The CDSC on Class B Shares will be waived in the following circumstances:

<PAGE>

      Redemption upon the death or disability of the shareholder, plan
     participant, or beneficiary.1
      Minimum required distributions from retirement plan accounts for
     shareholders 70 1/2 and older.2
      The return of an excess contribution or deferral amounts, pursuant to
     sections 408(d)(4) or (5), 401(k)(8), 402(g)(2), or 401(m)(6) of the
     Internal Revenue Code.
      Involuntary redemptions of accounts under procedures set forth by the
     Fund's Board of Trustees/Directors.
      A single annual withdrawal under a systematic withdrawal plan of up to
     10% per year of the shareholder's account balance.3

Class C
If you choose Class C, there is no front-end sales charge like Class A, but if
you sell the shares within the first year, you will have to pay a 1% CDSC.
Class C may be a good choice for you if you plan to buy shares and hold them
for at least 1 year, but not more than five or six years.

More on Comparison of Classes
The Example at the beginning of this prospectus compares the expenses of each
class, with and without redemptions. The Example includes both direct expenses
that you pay, such as the sales charges, and indirect expenses that are paid
by each Fund. The indirect expenses include management, shareholder servicing,
and 12b-1 fees. These fees may vary from class to class and can impact your
total return. Consider your investment goals and time period for investing to
help decide which class is best for you.

Distribution and Service Fees
Each Fund has adopted a plan under Rule 12b-1 of the Investment Company Act of
1940 that allows the Fund to pay distribution fees for the sale and
distribution of its shares. The distribution plan also pays service fees to
persons (such as your financial professional) for services provided to
shareholders. Because these fees are paid out of a Fund's assets on an ongoing
basis, over time, these fees will increase the cost of your investment and may
cost you more than paying other types of sales charges. Please see Exhibit B
for more service fee information.

1 "Disability" means a total disability as evidenced by a determination by the
federal Social Security Administration.
2 The maximum amount subject to this waiver is based only upon the
shareholder's Calvert Group retirement accounts.
3 This systematic withdrawal plan requires a minimum account balance of
$50,000 to be established.

<PAGE>

The table below shows the maximum annual percentage payable under the
distribution plan, and the amount actually paid by each Fund for the most
recent fiscal year. The fees are based on average daily net assets of the
particular Class.

IMPORTANT - HOW SHARES ARE PRICED
The price of shares is based on each Fund's net asset value ("NAV"). NAV is
computed by adding the value of a Fund's holdings plus other assets,
subtracting liabilities, and then dividing the result by the number of shares
outstanding. If a Fund has more than one class of shares, the NAV of each
class will be different, depending on the number of shares outstanding for
each class.

Portfolio securities and other assets are valued based on market quotations,
except that securities maturing within 60 days are valued at amortized cost.
CSIF Money Market is valued according to the "amortized cost" method, which is
intended to stabilize the NAV at $1 per share. If market quotations are not
readily available, securities are valued by a method that the Fund's Board of
Trustees/Directors believes accurately reflects fair value.

The NAV is calculated as of the close of each business day, which coincides
with the closing of the regular session of the New York Stock Exchange
("NYSE") (normally 4 p.m. ET). Each Fund is open for business each day the
NYSE is open. Please note that there are some federal holidays, however, such
as Columbus Day and Veterans' Day, when the NYSE is open and the Fund is open
but purchases cannot be made due to the closure of the banking system.

Some Funds hold securities that are primarily listed on foreign exchanges that
trade on days when the NYSE is closed. These Funds do not price shares on days
when the NYSE is closed, even if foreign markets may be open. As a result, the
value of the Fund's shares may change on days when you will not be able to buy
or sell your shares.

WHEN YOUR ACCOUNT WILL BE CREDITED
Your purchase will be processed at the next NAV calculated after your order is
received in good order. All of your purchases must be made in US dollars and
checks must be drawn on US

<PAGE>

banks. No cash will be accepted. No credit card or credit loan checks will be
accepted. Each Fund reserves the right to suspend the offering of shares for a
period of time or to reject any specific purchase order. As a convenience,
check purchases received at Calvert's office in Bethesda, Maryland will be
sent by overnight delivery to the Transfer Agent and will be credited the next
business day upon receipt. Any check purchase received without an investment
slip may cause delayed crediting. If your check does not clear your bank, your
purchase will be canceled and you will be charged a $10 fee plus any costs
incurred. Check or electronic funds transfer purchases will be on hold for up
to 10 business days. All purchases will be confirmed and credited to your
account in full and fractional shares (rounded to the nearest 1/1000th of a
share).

CSIF Money Market
Your purchase will be credited at the net asset value calculated after your
order is received and accepted. If the Transfer Agent receives your wire
purchase by 5 p.m. ET, your account will begin earning dividends on the next
business day. Exchanges begin earning dividends the next business day after
the exchange request is received by mail or telephone. Purchases received by
check will begin earning dividends the next business day after they are
credited to the account. CSIF Money Market may send monthly statements in lieu
of confirmations of purchases and redemptions.

ACCOUNT SERVICES
By signing up for services when you open your account, you avoid having to
obtain a signature guarantee. If you wish to add services at a later date, a
signature guarantee to verify your signature may be obtained from any bank,
trust company and savings and loan association, credit union, broker-dealer
firm or member of a domestic stock exchange. A notary public cannot provide a
signature guarantee.

CALVERT MONEY CONTROLLER

funds transfer without the time delay of mailing a check or the added expense
of a wire. Use this service to transfer up to $300,000 electronically. Allow
one or two business days after you

<PAGE>

place your request for the transfer to take place. Money transferred to
purchase new shares will be subject to a hold of up to 10 business days before
redemption requests will be honored. Transaction requests must be received by
4 p.m. ET. You may request this service on your initial account application.
Calvert Money Controller transactions returned for insufficient funds will
incur A $25 charge.

TELEPHONE TRANSACTIONS
You may purchase, redeem, or exchange shares, wire funds and use Calvert Money
Controller by telephone if you have pre-authorized service instructions. You
receive telephone privileges automatically when you open your account unless
you elect otherwise. For our mutual protection, the Fund, the shareholder
servicing agent and their affiliates use precautions such as verifying
shareholder identity and recording telephone calls to confirm instructions
given by phone. A confirmation statement is sent for most transactions; please
review this statement and verify the accuracy of your transaction immediately.

EXCHANGES
Calvert Group offers a wide variety of investment options that includes common
stock funds, tax-exempt and corporate bond funds, and money market funds (call
your broker or Calvert representative for more information). We make it easy
for you to purchase shares in other Calvert funds if your investment goals
change. The exchange privilege offers flexibility by allowing you to exchange
shares on which you have already paid a sales charge from one mutual fund to
another at no additional charge.

Complete and sign an account application, taking care to register your new
account in the same name and taxpayer identification number as your existing
Calvert account(s). Exchange instructions may then be given by telephone if
telephone redemptions have been authorized and the shares are not in
certificate form.

Before you make an exchange, please note the following:
Each exchange represents the sale of shares of one Fund and the purchase of
shares of another. Therefore, you could realize a taxable gain or loss.

You may exchange shares acquired by reinvestment of dividends or distributions
into another Calvert Fund at no additional charge.

Shares may only be exchanged for shares of the same class of another Calvert
Fund.

No CDSC is imposed on exchanges of shares subject to a CDSC at the time of the
exchange. The applicable CDSC is imposed at the time the shares acquired by
the exchange are redeemed.

<PAGE>

Shareholders (and those managing multiple accounts) who make two purchases and
two exchange redemptions of shares of the same Fund during any six-month
period will be given written notice and may be prohibited from placing
additional investments. This policy does not prohibit a shareholder from
redeeming shares of any Fund, and does not apply to trades solely between
money market funds.

Each Fund reserves the right to terminate or modify the exchange privilege
with 60 days' written notice.

COMBINED GENERAL MAILINGS (Householding)
Multiple accounts with the same social security number will receive one
mailing per household of information such as prospectuses and semi-annual and
annual reports. You may request further grouping of accounts to receive fewer
mailings. Separate statements will be generated for each separate account and
will be mailed in one envelope for each combination above.

SPECIAL SERVICES AND CHARGES
Each Fund pays for shareholder services but not for special services that are
required by a few shareholders, such as a request for a historical transcript
of an account or a stop payment on a draft. You may be required to pay a fee
for these special services; for example, the fee for stop payments is $25.

If you are purchasing shares through a program of services offered by a
broker/dealer or financial institution, you should read the program materials
together with this Prospectus. Certain features may be modified in these
programs. Investors may be charged a fee if they effect transactions in Fund
shares through a broker or agent.

MINIMUM ACCOUNT BALANCE
Please maintain a balance in each of your Fund accounts of at least $1,000 per
class ($5,000 for the CSIF Managed Index). If the balance in your account
falls below the minimum during a month, a fee of may be charged to your
account (CSIF Money Market, $3.00/month, and CSIF Managed Index, $1.00/month).
If the balance in your account falls below the minimum during a month, your
account may be closed and the proceeds mailed to the address of record. You
will receive notice that your account is below the minimum, and will be closed
or charged if the balance is not brought up to the required minimum amount
within 30 days.

<PAGE>

DIVIDENDS, CAPITAL GAINS AND TAXES

Each Fund pays dividends from its net investment income as shown below. Net
investment income consists of interest income, net short-term capital gains,
if any, and dividends declared and paid on investments, less expenses.
Distributions of net short-term capital gains (treated as dividends for tax
purposes) and net long-term capital gains, if any, are normally paid once a
year; however, the Funds do not anticipate making any such distributions
unless available capital loss carryovers have been used or have expired.
Dividend and distribution payments will vary between classes; dividend
payments are anticipated to be generally higher for Class A shares.

CSIF Money Market                       Accrued daily, paid monthly
CSIF Bond                               Paid monthly
CSIF Balanced                           Paid quarterly
CSIF Equity                             Paid annually
CSIF Managed Index                      Paid annually
CWVF International Equity               Paid annually
Capital Accumulation                    Paid annually
New Vision Small Cap                    Paid annually

Dividend payment options
Dividends and any distributions are automatically reinvested in the same Fund
at NAV (without sales charge), unless you elect to have amounts of $10 or more
paid in cash (by check or by Calvert Money Controller). Dividends and
distributions from any Calvert Group Fund may be automatically invested in an
identically registered account in any other Calvert Group Fund at NAV. If
reinvested in the same account, new shares will be purchased at NAV on the
reinvestment date, which is generally 1 to 3 days prior to the payment date.
You must notify the Funds in writing to change your payment options. If you
elect to have dividends and/or distributions paid in cash, and the US Postal
Service returns the check as undeliverable, it, as well as future dividends
and distributions, will be reinvested in additional shares. No dividends will
accrue on amounts represented by uncashed distribution or redemption checks.

Buying a Dividend (Not Applicable to Money Market Funds)
At the time of purchase, the share price of each class may reflect
undistributed income, capital gains or unrealized appreciation of securities.
Any income or capital gains from these amounts which are later distributed to
you are fully taxable. On the record date for a distribution, share value is
reduced by the amount of the distribution. If you buy shares just before the
record date ("buying a dividend") you will pay the full price for the shares
and then receive a portion of the price back as a taxable distribution.

<PAGE>

Federal Taxes
In January, each Fund will mail you Form 1099-DIV indicating the federal tax
status of dividends and any capital gain distributions paid to you during the
past year. Generally, dividends and distributions are taxable in the year they
are paid. However, any dividends and distributions paid in January but
declared during the prior three months are taxable in the year declared.
Dividends and distributions are taxable to you regardless of whether they are
taken in cash or reinvested. Dividends, including short-term capital gains,
are taxable as ordinary income. Distributions from long-term capital gains are
taxable as long-term capital gains, regardless of how long you have owned
shares.

For Non-Money Market Funds
You may realize a capital gain or loss when you sell or exchange shares. This
capital gain or loss will be short- or long-term, depending on how long you
have owned the shares which were sold. In January, these Funds will mail you
Form 1099-B indicating the total amount of all sales, including exchanges. You
should keep your annual year-end account statements to determine the cost
(basis) of the shares to report on your tax returns.

Other Tax Information
In addition to federal taxes, you may be subject to state or local taxes on
your investment, depending on the laws in your area. You will be notified to
the extent, if any, that dividends reflect interest received from US
government securities. Such dividends may be exempt from certain state income
taxes.

Taxpayer Identification Number
If we do not have your correct Social Security or Taxpayer Identification
Number ("TIN") and a signed certified application or Form W-9, Federal law
requires us to withhold 31% of your reportable dividends, and possibly 31% of
certain redemptions. In addition, you may be subject to a fine by the Internal
Revenue Service. You will also be prohibited from opening another account by
exchange. If this TIN information is not received within 60 days after your
account is established, your account may be redeemed (closed) at the current
NAV on the date of redemption. Calvert Group reserves the right to reject any
new account or any purchase order for failure to supply a certified TIN.

HOW TO SELL SHARES

You may redeem all or a portion of your shares on any day your Fund is open
for business, provided the amount requested is not on hold. When you purchase
by check or with Calvert Money Controller (electronic funds transfer), the
purchase will be on hold for up to 10 business days from the date of receipt.
During the hold period, redemptions proceeds will not be sent until the
Transfer Agent is reasonably satisfied that the purchase payment has been
collected. Drafts written on CSIF Money Market during the hold period will be
returned for uncollected funds.
Your shares will be redeemed at the next NAV calculated after your redemption
request is

<PAGE>

received and accepted (less any applicable CDSC). The proceeds will normally
be sent to you on the next business day, but if making immediate payment could
adversely affect your Fund, it may take up to seven (7) days to make payment.
Calvert Money Controller redemptions generally will be credited to your bank
account on the second business day after your phone call. The Funds have the
right to redeem shares in assets other than cash for redemption amounts
exceeding, in any 90-day period, $250,000 or 1% of the net asset value of the
affected Fund, whichever is less. When the NYSE is closed (or when trading is
restricted) for any reason other than its customary weekend or holiday
closings, or under any emergency circumstances as determined by the Securities
and Exchange Commission, redemptions may be suspended or payment dates
postponed. Please note that there are some federal holidays, however, such as
Columbus Day and Veterans' Day, when the NYSE is open and the Fund is open but
redemptions cannot be made due to the closure of the banking system.

Follow these suggestions to ensure timely processing of your redemption
request:

By Telephone
You may redeem shares from your account by telephone and have your money
mailed to your address of record or electronically transferred or wired to a
bank you have previously authorized. A charge of $5 may be imposed on wire
transfers of less than $1,000.

Written Requests
Calvert Group, P.O. Box 419544, Kansas City, MO 64141-6544
Your letter should include your account number and fund and the number of
shares or the dollar amount you are redeeming. Please provide a daytime
telephone number, if possible, for us to call if we have questions. If the
money is being sent to a new bank, person, or address other than the address
of record, your letter must be signature guaranteed.

Draftwriting (CSIF Money Market Portfolio only)
You may redeem shares in your CSIF Money Market Portfolio account by writing a
draft for at least $250. If you complete and return the signature card for
Draftwriting, the Portfolio will mail bank drafts to you, printed with your
name and address. Drafts may not be ordered until your initial purchase has
cleared. Generally, there is no charge to you for this service, but CSIF Money
Market will charge a service fee for drafts returned for insufficient funds.
CSIF Money Market will charge $25 for any stop payment on drafts. As a service
to shareholders, shares may be automatically transferred between your Calvert
accounts to cover drafts you have written. The signature of only one
authorized signer is required to honor a draft.

Systematic Check Redemptions
If you maintain an account with a balance of $10,000 or more, you may have up
to two (2) redemption checks for a fixed amount sent to you on the 15th of the
month, simply by sending a letter with all information, including your account
number, and the dollar amount ($100 minimum). If you would like a regular
check mailed to another person or place, your letter must be

<PAGE>

signature guaranteed. Unless they otherwise qualify for a waiver, Class B or
Class C shares redeemed by Systematic Check Redemption will be subject to the
Contingent Deferred Sales Charge.

Corporations and Associations
Your letter of instruction and corporate resolution should be signed by
person(s) authorized to act on the account, accompanied by signature
guarantee(s).

Trusts
Your letter of instruction should be signed by the Trustee(s) (as Trustee(s)),
with a signature guarantee. (If the Trustee's name is not registered on your
account, please provide a copy of the trust document, certified within the
last 60 days.)

Through your Dealer
Your dealer must receive your request before the close of regular trading on
the NYSE to receive that day's NAV. Your dealer will be responsible for
furnishing all necessary documentation to Calvert Group and may charge you for
services provided.

FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the Funds'
financial performance for the past 5 years (or if shorter, the period of the
Fund's operations). Certain information reflects financial results for a
single share, by Fund and Class. The total returns in the table represent the
rate that an investor would have earned (or lost) on an investment in a Fund
(assuming reinvestment of all dividends and distributions), and does not
reflect any applicable front- or back-end sales charge. This information has
been audited by PricewaterhouseCoopers LLP whose report, along with a Fund's
financial statements, are included in the Fund's annual report, which is
available upon request.

EXHIBIT A
REDUCED SALES CHARGES (CLASS A ONLY)

You may qualify for a reduced sales charge through several purchase plans
available. You must notify the Fund at the time of purchase to take advantage
of the reduced sales charge.

Rights of Accumulation can be applied to several accounts
Class A sales charge breakpoints are automatically calculated for each account
based on the higher of cost or current value of shares previously purchased.
This privilege can be applied to a family group or other qualified group* upon
request. Shares could then be purchased at the reduced sales charge which
applies to the entire group; that is, based on the higher of cost or current
value of shares previously purchased and currently held by all the members of
the group.

Letter of Intent
If you (or your group, as described above) plan to purchase $50,000 or more of
Calvert Fund shares over the next 13 months, your sales charge may be reduced
through a "Letter of Intent." You pay the lower sales charge applicable to the
total amount you plan to invest over the 13-month period, excluding any money
market fund purchases, instead of the higher 4.75% sales charge. Part of your
shares will be held in escrow, so that if you do not invest the amount
indicated, you will have to pay the sales charge applicable to the smaller
investment actually made. For more information, see the SAI.

Retirement Plans Under Section 457, Section 403(b)(7), or Section 401(k)
There is no sales charge on shares purchased for the benefit of a retirement
plan under section 457 of the Internal Revenue Code of 1986, as amended
("Code"), or for a plan qualifying under section 403(b) or 401(k) of the Code
if, at the time of purchase, (i) Calvert Group has been notified in writing
that the 403(b) or 401(k) plan has at least 200 eligible employees and is not
sponsored by a K-12 school district, or (ii) the cost or current value of
shares a 401(k) plan has in Calvert Group of Funds (except money market funds)
is at least $1 million.

Neither the Funds, nor Calvert Distributors, Inc. ("CDI"), nor any affiliate
thereof will reimburse a plan or participant for any sales charges paid prior
to receipt of such written communication and confirmation by Calvert Group.
Plan administrators should send requests for the waiver of sales charges based
on the above conditions to: Calvert Group Retirement Plans, 4550 Montgomery
Avenue, Suite 1000N, Bethesda, Maryland 20814.

* A "qualified group" is one which:
1.    has been in existence for more than six months, and
2.    has a purpose other than acquiring shares at a discount, and
3.    satisfies uniform criteria which enable CDI and brokers offering shares
     to realize economies of scale in distributing such shares.

A qualified group must have more than 10 members, must be available to arrange
for group meetings between representatives of CDI or brokers distributing
shares, must agree to include sales and other materials related to the Funds
in its publications and mailings to members at reduced or no cost to CDI or
brokers. A pension plan is not a qualified group for rights of accumulation.

<PAGE>

Other Circumstances
There is no sales charge on shares of any Fund of the Calvert Group of Funds
sold to (i) current or retired Directors, Trustees, or Officers of the Calvert
Group of Funds, employees of Calvert Group, Ltd. and its affiliates, or their
family members; (ii) CSIF Advisory Council Members, directors, officers, and
employees of any subadvisor for the Calvert Group of Funds, employees of
broker/dealers distributing the Fund's shares and immediate family members of
the Council, subadvisor, or broker/dealer; (iii) Purchases made through a
Registered Investment Advisor; (iv) Trust departments of banks or savings
institutions for trust clients of such bank or institution, (v) Purchases
through a broker maintaining an omnibus account with the Fund, provided the
purchases are made by (a) investment advisors or financial planners placing
trades for their own accounts (or the accounts of their clients) and who
charge a management, consulting, or other fee for their services; or (b)
clients of such investment advisors or financial planners who place trades for
their own accounts if such accounts are linked to the master account of such
investment advisor or financial planner on the books and records of the broker
or agent; or (c) retirement and deferred compensation plans and trusts,
including, but not limited to, those defined in section 401(a) or section
403(b) of the I.R.C., and "rabbi trusts."

Established Accounts
Shares of CSIF Balanced may be sold at net asset value to you if your account
was established on or before July 17, 1986.

Dividends and Capital Gain Distributions from other Calvert Group Funds
You may prearrange to have your dividends and capital gain distributions from
another Calvert Group Fund automatically invested in another account with no
additional sales charge.

Purchases made at NAV
Except for money market funds, if you make a purchase at NAV, you may exchange
that amount to another Calvert Group Fund at no additional sales charge.

Reinstatement Privilege
If you redeem shares and then within 30 days decide to reinvest in the same
Fund, you may do so at the net asset value next computed after the
reinvestment order is received, without a sales charge. You may use the
reinstatement privilege only once. The Funds reserve the right to modify or
eliminate this privilege.

EXHIBIT B
SERVICE FEES AND ARRANGEMENTS WITH DEALERS

Calvert Distributors, Inc., each Fund's underwriter, pays dealers a
commission, or reallowance (expressed as a percentage of the offering price
for Class A, and a percentage of amount invested for Class B and C) when you
purchase shares of non-money market funds. CDI also pays dealers an ongoing
service fee while you own shares of that Fund (expressed as an annual
percentage rate of average daily net assets held in Calvert accounts by that
dealer). The table below shows the amount of payment which differs depending
on the Class.

charge. CDI may also pay additional concessions, including non-cash
promotional incentives, such as merchandise or trips, to brokers employing
registered representatives who have sold or are expected to sell a minimum
dollar amount of shares of the Funds and/or shares of other Funds underwritten
by CDI. CDI may make expense reimbursements for special training of a broker's
registered representatives, advertising or equipment, or to defray the
expenses of sales contests. CAMCO, CDI, or their affiliates may pay certain
broker-dealers and/or other persons, for the sale and distribution of the
securities or for services to the Fund. Payments may include additional
compensation based on assets held through that firm beyond the regularly
scheduled rates, and finder's fees. CDI pays dealers a finder's fee on Class A
shares purchased at NAV in accounts with $1 million or more (excluding CSIF
Money Market.) The finder's fee is 1% of the NAV purchase amount on the first
$2 million, .80% on $2 to $3 million, .50% on $3 to $50 million, .25% on $50
to $100 million, and .15 over $1 million. All payments will be in compliance

CSIF Balanced (Note: Formerly known as CSIF Managed Growth)

Advisor
Calvert Asset Management Company, Inc.
Subadvisors                                  Brown Capital Management, Inc.
                                               NCM Capital Management, Inc.

Objective
CSIF Balanced seeks to achieve a competitive total return through an actively
managed portfolio of stocks, bonds and money market instruments which offer
income and capital growth opportunity and which satisfy the investment and
social criteria.

(Note: This objective is subject to shareholder approval expected at a
shareholder meeting in late February, 1999. Unless and until shareholders
approve the new objective, the current objective for CSIF shall continue in
effect, which is CSIF Balanced "seeks to achieve a total return above the rate
of inflation, through an actively managed, diversified portfolio of common and
preferred stocks, bonds and money market instruments, which offer income and
capital growth opportunity and which satisfy the investment and social
criteria.)

Principal investment strategies
The Fund typically invests about 60% of its assets in stocks and 40% in bonds
or other fixed-income investments. Stock investments are primarily common
stock in large-cap companies, while the fixed-income investments are primarily
a wide variety of investment grade bonds. CSIF Balanced invests in a
combination of stocks, bonds and money market instruments in an attempt to
provide a complete investment portfolio in a single product. The Advisor
rebalances the Fund quarterly to adjust for changes in market value. The Fund
is a large-cap, growth-oriented U.S. domestic portfolio, although it may have
other investments, including some foreign securities and some mid-cap stocks.
For the equity portion, the Fund seeks companies with better than average
expected growth rates at lower than average valuations. The fixed-income
portion reflects an active trading strategy, seeking total return and focuses
on a duration target approximating the Lehman Aggregate Bond Index.

Equity investments are selected by the two Subadvisors, while the Advisor
manages the fixed-income assets and determines the overall mix for the Fund
depending upon its view of market conditions and economic outlook.

The Fund invests with the philosophy that long-term rewards to investors will
come from those organizations whose products, services, and methods enhance
the human condition and the traditional American values of individual
initiative, equality of opportunity and cooperative effort. Investments are
selected on the basis of their ability to contribute to the dual objectives of
financial soundness and social criteria. See "Investment Selection Process."

- --------------------------------------------------------------------------------
Principal risks:
- --------------------------------------------------------------------------------
You could lose money on your investment in the Fund, or the Fund could
underperform for any of the following reasons:
         o The stock or bond market goes down
         o The individual stocks and bonds in the Fund do not perform as well
as expected
         o For the fixed-income portion of the Fund, the Advisor's forecast as
to interest rates is not correct
         o For the foreign securities held in the Fund, if foreign currency
values go down versus the U.S. dollar
         o The Advisor's allocation among different sectors of the stock and
bond markets does not perform as well as expected

An investment in the Fund is not a bank deposit and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other
government agency.

Bar Chart and Performance Table
The bar chart and table below show the Fund's annual returns and its long-term
performance. Because Class I shares were not offered prior to 1999, the chart
shows the performance of the Class A shares at NAV. Class I returns would have
been similar, except for its lower expenses. The table compares the Fund's
performance over time to that of the Standard & Poor's 500 Index and the
Lehman Aggregate Bond Index. It also shows the Fund's returns compared to the
Lipper Balanced Funds Index. The average total return table shows returns for
Class A shares with the maximum sales charge deducted. No sales charge has
been applied to the index used for comparison in the table. Again, Class I
returns would have been similar, except for lower expenses and no sales
charges. The Fund's past performance does not necessarily indicate how the
Fund will perform in the future.

CSIF Managed Index

Advisor                              Calvert Asset Management Company, Inc.
Subadvisor                                     State Street Global Advisors

Objective
CSIF Managed Index seeks a total return after expenses which exceeds over time
the total return of the Russell 1000 Index. It seeks to obtain this objective
while maintaining risk characteristics similar to those of the Russell 1000
Index and through investments in stocks that meet the Fund's investment and
social criteria. This objective may be changed by the Fund's Board of
Trustees/Directors without shareholder approval.

Principal investment strategies:
The Fund invests in stocks that meet the social criteria and creates a
portfolio whose characteristics closely resemble the characteristics of the
Russell 1000 Index, while emphasizing the stocks which it believes offer the
greatest potential of return.

CSIF Managed Index follows an enhanced index management strategy. Instead of
passively holding a representative basket of securities designed to match the
Russell 1000 Index, the Subadvisor actively uses a proprietary analytical
model to attempt to enhance the Fund's performance, relative to the Index. The
Fund may purchase stocks not in the Russell 1000 Index, but at least 65% of
the Fund's total assets will be invested in stocks that are in the Index. Any
investments not in the Index will meet the Fund's social screening criteria
and be selected to closely mirror the Index's risk/return characteristics. The
Subadvisor rebalances the Fund quarterly to maintain its relative exposure to
the Index.

The first step of the investment strategy is to identify those stocks in the
Russell 1000 Index which meet the Fund's social screening criteria. From this
list of stocks, the Subadvisor chooses stocks that closely mirror the Index in
terms of various factors such as industry weightings, capitalization, and
yield. Even though certain industries may be eliminated from the Fund by the
screens, the factor model permits mathematical substitutes which the
Subadvisor expects to mimic the return characteristics of the missing
industries and stocks.

The final step in the process is to apply the Subadvisor's proprietary
valuation method which attempts to identify the stocks which have the greatest
potential for superior performance. Each security identified for potential
investment is ranked according to two separate measures: value and momentum of
market sentiment. These two measures combine to create a single composite
score of each stock's attractiveness. The Fund is constructed from securities
that meet its social criteria, weighted through a mathematical process that
seeks to reduce risk vis-a-vis the Russell 1000 Index. The Subadvisor expects
to hold between 100 and 150 stocks.

The Russell 1000 Index measures the performance of the 1,000 largest U.S.
companies based on total market capitalization. The Index is adjusted, or
reconstituted, annually. As of the latest reconstitution, the average market
capitalization of the Russell 1000 was approximately $7.6 billion.

Tracking the Index
The Subadvisor expects a tracking error over time of no more than 2.5%,
although there can be no guarantee such results will be achieved. The Fund's
ability to track the Index will be monitored by analyzing returns to ensure
that the returns are reasonably consistent with Index returns. Any deviations
of realized returns from the Index which are in excess of those expected will
be analyzed for sources of variance. Where variations are deemed to be
systematic or associated with a particular feature of the investment process,
the constraints on the Fund associated with that factor may be adjusted to
ensure a higher degree of correlation to the Index.

The Fund invests with the philosophy that long-term rewards to investors will
come from those organizations whose products, services, and methods enhance
the human condition and the traditional American values of individual
initiative, equality of opportunity and cooperative effort. Investments are
selected on the basis of their ability to contribute to the dual objectives of
financial soundness and social criteria. See "Investment Selection Process."

- --------------------------------------------------------------------------------
Principal risks:
- --------------------------------------------------------------------------------

You could lose money on your investment in the Fund, or the Fund could
underperform the stock market for any of the following reasons:

o        The stock market or the Russell 1000 Index goes down
o        The individual stocks in the Fund or the index modeling portfolio do
not perform as well as expected
o        An index fund has operating expenses; a market index does not. The
Fund - while expected to track its target index as closely as possible while
satisfying its own investment and social criteria - will not be able to match
the performance of the index exactly

An investment in the Fund is not a bank deposit and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other
government agency. The Fund is not sponsored, sold, promoted or endorsed by
the Frank Russell Company.

Subadvisors                      Atlanta Capital Management Company, L.L.C.

Objective
CSIF Equity seeks growth of capital through investment in stocks of issuers in
industries believed to offer opportunities for potential capital appreciation
and which meet the Fund's investment and social criteria.

Principal investment strategies:
The Fund invests primarily in the common stocks of large-cap companies having,
on average, market capitalization of at least $1 billion. Investment returns
will be mostly from changes in the price of the Fund's holdings (capital
appreciation).

The Subadvisor looks for growing companies with a history of steady earnings
growth. Companies are selected based on the Subadvisor's opinion that the
company has the ability to sustain growth through growing profitability and
that the stock is favorably priced with respect to those growth expectations.

The Fund invests with the philosophy that long-term rewards to investors will
come from those organizations whose products, services, and methods enhance
the human condition and the traditional American values of individual
initiative, equality of opportunity and cooperative effort. Investments are
selected on the basis of their ability to contribute to the dual objectives of
financial soundness and social criteria. See "Investment Selection Process."

Calvert Capital Accumulation

Advisor                              Calvert Asset Management Company, Inc.
Subadvisor                                   Brown Capital Management, Inc.

Objective
Capital Accumulation seeks to provide long-term capital appreciation by
investing primarily in mid-cap stocks that meet the Fund's investment and
social criteria. This objective may be changed by the Fund's Board of
Trustees/Directors without shareholder approval.

Principal investment strategies
Investments are primarily in the common stocks of mid-size companies.
Returns in the Fund will be mostly from the changes in the price of the Fund's
holdings (capital appreciation.) The Fund currently defines mid-cap companies
as those within the range of market capitalizations of the S & P's Mid-cap 400
Index. Most companies in the Index have a capitalization of $500 million to
$10 billion. Stocks chosen for the Fund combine growth and value
characteristics or offer the opportunity to buy growth at a reasonable price.

The Subadvisor favors companies which have an above market average prospective
growth rate, but sell at below market average valuations. The Subadvisor
evaluates each stock in terms of its growth potential, the return for risk free
investments and the risk and reward potential for the company to determine a
reasonable price for the stock.

The Fund invests with the philosophy that long-term rewards to investors will
come from those organizations whose products, services, and methods enhance
the human condition and the traditional American values of individual
initiative, equality of opportunity and cooperative effort. Investments are
selected on the basis of their ability to contribute to the dual objectives of
financial soundness and social criteria. See "Investment Selection Process."

- --------------------------------------------------------------------------------
Principal risks

You could lose money on your investment in the Fund, or the Fund could
underperform for any of the following reasons:

o The stock market goes down
o The individual stocks in the Fund do not perform as well as expected
o The Fund is non-diversified. Compared to other funds, the Fund may invest
more of its assets in a smaller number of companies. Gains or losses on a
single stock may have greater impact on the Fund.

An investment in the Fund is not a bank deposit and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other
government agency.

Calvert World Values International Equity Fund

Advisor                              Calvert Asset Management Company, Inc.
Subadvisor                             Murray Johnstone International, Ltd.

Objective
CWVF International Equity seeks to provide a high total return consistent with
reasonable risk by investing primarily in a globally diversified portfolio of
stocks that meet the Fund's investment and social criteria.

Principal investment strategies
The Fund identifies those countries with markets and economies that it
believes currently provide the most favorable climate for investing. The Fund
invests primarily in the common stocks of mid- to large-cap companies using a
value approach. The Subadvisor selects countries based on a "20 questions"
model which uses macro- and micro-economic inputs to rank the attractiveness
of markets in various countries. Within each country, the Subadvisor uses
valuation techniques that have been shown to best determine value within that
market. In some countries, the valuation process may favor the comparison of
price-to-cash-flow while in other countries, price-to-sales or price-to-book
may be more useful in determining which stocks are undervalued.

The Fund invests primarily in more developed economies and markets. No more
than 5% of Fund assets are invested in the U.S. (excluding High Social Impact
and Special Equities investments).

o The stock markets (including those outside the U.S.) go down
o The individual stocks in the Fund do not perform as well as expected
o Foreign currency values go down versus the U.S. dollar

An investment in the Fund is not a bank deposit and is not insured or

Bar Chart and Performance Table
The bar chart and table below show the Fund's annual returns and its long-term
performance. Because Class I shares were not offered prior to 1999, the chart
shows the performance of the Class A shares at NAV. Class I returns would have
been similar, except for its lower expenses. The table compares the Fund's
performance over time to that of the Morgan Stanley Capital International EAFE
Index. It also shows the Fund's returns compared to the Lipper International
Funds Index. The average total return table shows returns for Class A shares
with the maximum sales charge deducted. No sales charge has been applied to
the index used for comparison in the table. Again, Class I returns would have
been similar, except for lower expenses and no sales charges. The Fund's past
performance does not necessarily indicate how the Fund will perform in the
future.

Calvert New Vision Small Cap

Advisor                              Calvert Asset Management Company, Inc.
Subadvisor                                      Awad Asset Management, Inc.

Objective
New Vision Small Cap seeks to provide long-term capital appreciation by
investing primarily in small-cap stocks that meets the Fund's investment and
social criteria. This objective may be changed by the Fund's Board of
Trustees/Directors without shareholder approval.

Principal Investment Strategies
At least 65% of the Fund's assets will be invested in the common stocks of
small-cap companies. Returns in the Fund will be mostly from the changes in
the price of the Fund's holdings (capital appreciation). The Fund currently
defines small-cap companies as those with market capitalization of $1 billion
or less at the time the Fund initially invests.

The Fund invests with the philosophy that long-term rewards to investors will
come from those organizations whose products, services, and methods enhance
the human condition and the traditional American values of individual
initiative, equality of opportunity and cooperative effort. Investments are
selected on the basis of their ability to contribute to the dual objectives of
financial soundness and social criteria. See "Investment Selection Process."

You could lose money on your investment in the Fund, or the Fund could
underperform for any of the following reasons:

o The stock market goes down
o The individual stocks in the Fund do not perform as well as expected
o Prices of small-cap stocks may respond to market activity differently than
larger more established companies

An investment in the Fund is not a bank deposit and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other
government agency.

CSIF Bond

Advisor                              Calvert Asset Management Company, Inc.

Objective
CSIF Bond seeks to provide as high a level of current income as is consistent
with prudent investment risk and preservation of capital through investment in
bonds and other straight debt securities meeting the Fund's investment and
social criteria.

Principal investment strategies:
The Fund uses an active strategy, seeking relative value to earn incremental
income. The Fund typically invests at least 65% of its assets in investment
grade debt securities.

The Fund invests with the philosophy that long-term rewards to investors will
come from those organizations whose products, services, and methods enhance
the human condition and the traditional American values of individual
initiative, equality of opportunity and cooperative effort. Investments are
selected on the basis of their ability to contribute to the dual objectives of
financial soundness and social criteria. See "Investment Selection Process."

- --------------------------------------------------------------------------------
Principal risks:
- --------------------------------------------------------------------------------
You could lose money on your investment in the Fund, or the Fund could
underperform , most likely for any of the following reasons:

o The bond market goes down
o The individual bonds in the Fund do not perform as well as expected
o The Advisor's forecast as to interest rates is not correct
o The Advisor's allocation among different sectors of the bond market does not
perform as well as expected
o The Fund is non-diversified. Compared to other funds, the Fund may invest
more of its assets in a smaller number of companies. Gains or losses on a
single bond may have greater impact on the Fund.
(The Fund's non-diversified status is subject to shareholder approval expected
at a shareholder meeting in late February 1999. Unless and until the
shareholders approve the changes, the Fund will be diversified.)

An investment in the Fund is not a bank deposit and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other
government agency.

Bar Chart and Performance Table
The bar chart and table below show the Fund's annual returns and its long-term
performance. Because Class I shares were not offered prior to 1999, the chart
shows the performance of the Class A shares at NAV. Class I returns would have
been similar, except for its lower expenses. The table compares the Fund's
performance over time to that of the Lehman Aggregate Bond Index. It also

Explanation of Fees and Expenses Table
Expenses are based on estimates for the current fiscal year. Management fees
include the Subadvisory fees paid by the Advisor ("CAMCO") to the Subadvisors,
and, if applicable, the administrative fee paid by the Fund to Calvert
Administrative Services Company, an affiliate of CAMCO.

1 CAMCO has agreed to waive fees and/or reimburse expenses (net of any expense
offset arrangements) for all of the Funds' Class I shares through December 31,
1999. The contractual expense cap is shown as "Net Expenses", this is the
maximum amount that may be charged to the Funds for this period.
2 The Management fees for CSIF Balanced, CSIF Equity, and Calvert Capital
Accumulation have been restated to reflect changes expected to be approved by
shareholders in early 1999. See "About Calvert Group--Advisory Fees". If
shareholders do not approve the changes to the fees the Management fees and
Total annual fund operating expenses and Net Expenses, if applicable, would be
0.07% lower for CSIF Balanced, 0.14% lower for CSIF Equity, and 0.01% lower
for Calvert Capital Accumulation.
3 Expenses for New Vision Small Cap have been restated to reflect expenses
expected to be incurred in 1999.

Example
This example is intended to help you compare the cost of investing in a Fund
with the cost of investing in other mutual funds.
The example assumes that:

o You invest $1,000,000 in the Fund for the time periods indicated;
o Your investment has a 5% return each year; and
o The Fund's operating expenses remain the same.

Although your actual costs may be higher or lower, under these assumptions
your costs would be as follows if the Class I shares are held for 1, 3, 5 or
10 years:

Principal Investment Practices and Risks
The most concise description of each Fund's principal investment strategies
and associated risks is under the risk-return summary for each Fund. The Funds
are also permitted to invest in certain other investments and to use certain
investment techniques that have higher risks associated with them. On the
following pages are brief descriptions of the investments and techniques
summarized in the risk-return summary, along with certain additional
investment techniques and their risks.

For each of the investment practices listed, the table below shows each Fund's
limitations as a percentage of its assets and the principal types of risk
involved. (See the pages following the table for a description of the types of
risks). Numbers in this table show maximum allowable amount only; for actual
usage, consult the Fund's annual/semi-annual reports.

dollar-denominated receipts representing shares of a foreign issuer. ADRs are
traded on U.S. exchanges. See the SAI.
2 Excludes any high social impact investments.

<PAGE>

The Funds have additional investment policies and restrictions that are not
principal to their investment strategies (for example, repurchase agreements,
borrowing, pledging, and reverse repurchase agreements, securities lending,
when-issued securities and short sales.) These policies and restrictions are
discussed in the SAI.

Types of Investment Risk

Correlation risk
This occurs when a Fund "hedges"- uses one investment to offset the Fund's
position in another. If the two investments do not behave in relation to one
another the way Fund managers expect them to, then unexpected or undesired
results may occur. For example, a hedge may eliminate or reduce gains as well
as offset losses.

Credit risk
The risk that the issuer of a security or the counterparty to an investment
contract may default or become unable to pay its obligations when due.

Currency risk
Currency risk occurs when a Fund buys, sells or holds a security denominated
in foreign currency. Foreign currencies "float" in value against the U.S.
dollar. Adverse changes in foreign currency values can cause investment losses
when a Fund's investments are converted to U.S. dollars.

Extension risk
The risk that an unexpected rise in interest rates will extend the life of a
mortgage-backed security beyond the expected prepayment time, typically
reducing the security's value.

Information risk
The risk that information about a security or issuer or the market might not
be available, complete, accurate or comparable.

Interest rate risk
The risk that changes in interest rates will adversely affect the value of an
investor's securities. When interest rates rise, the value of fixed-income
securities will generally fall. Conversely, a drop in interest rates will
generally cause an increase in the value of fixed-income securities.
Longer-term securities and zero coupon/"stripped" coupon securities ("strips")
are subject to greater interest rate risk.

Leverage risk
The risk that occurs in some securities or techniques which tend to magnify
the effect of small changes in an index or a market. This can result in a loss
that exceeds the amount actually invested.

Liquidity risk
The risk that occurs when investments cannot be readily sold. A Fund may have
to accept a less-than-desirable price to complete the sale of an illiquid
security or may not be able to sell it at all.

Management risk
This risk exists in all mutual funds and means that a Fund's portfolio
management practices might not work to achieve their desired result.

Market risk
The risk that exists in all mutual funds and means the risk that securities
prices in a market, a sector or an industry will fluctuate, and that such
movements might reduce an investment's value.

Opportunity risk
The risk of missing out on an investment opportunity because the assets needed
to take advantage of it are committed to less advantageous investments or
strategies.

Political risk
The risk that may occur with foreign investments, and means that the value of
an investment may be adversely affected by nationalization, taxation, war,
government instability or other economic or political actions or factors.

Prepayment risk
The risk that unanticipated prepayments may occur, reducing the value of a
mortgage-backed security. The Fund must then reinvest those assets at the
current market rate, which may be lower.

Transaction risk
The risk that a Fund may be delayed or unable to settle a transaction or that
commissions and settlement expenses may be higher than usual.

Investment Selection Process

Investments are selected on the basis of their ability to contribute to the
dual objectives of financial soundness and social criteria.
Potential investments for a Fund are first selected for financial soundness
and then evaluated according to that Fund's social criteria. To the greatest
extent possible, Calvert Social Investment Fund (CSIF) and Calvert World
Values International Equity Fund (CWVF) seek to invest in companies that
exhibit positive accomplishments with respect to one or more of the social
criteria. Investments for all Funds must meet the minimum standards for all
its financial and social criteria.

Although each Fund's social criteria tend to limit the availability of
investment opportunities more than is customary with other investment
companies, CAMCO and the Subadvisors of the Funds believe there are sufficient
investment opportunities to permit full investment among issuers which satisfy
each Fund's investment and social objectives.

The selection of an investment by a Fund does not constitute endorsement or
validation by that Fund, nor does the exclusion of an investment necessarily
reflect failure to satisfy the Fund's social criteria. Investors are invited
to send a brief description of companies they believe might be suitable for
investment.

Socially Responsible Investment Criteria
The Funds invest in accordance with the philosophy that long-term rewards to
investors will come from those organizations whose products, services, and
methods enhance the human condition and the traditional American values of
individual initiative, equality of opportunity and cooperative effort. In
addition, we believe that there are long-term benefits in an investment
philosophy that demonstrates concern for the environment, labor relations,
human rights and community relations. Those enterprises that exhibit a social
awareness in these issues should be better prepared to meet future societal
needs. By responding to social concerns, these enterprises should not only
avoid the liability that may be incurred when a product or service is
determined to have a negative social impact or has outlived its usefulness,
but also be better positioned to develop opportunities to make a profitable
contribution to society. These enterprises should be ready to respond to
external demands and ensure that over the longer term they will be viable to
seek to provide a positive return to both investors and society as a whole.

Each Fund has developed social investment criteria, detailed below. These
criteria represent standards of behavior which few, if any, organizations
totally satisfy. As a matter of practice, evaluation of a particular
organization in the context of these criteria will involve subjective judgment
by CAMCO and the Subadvisors. All social criteria may be changed by the Board
of Trustees/Directors without shareholder approval.

Calvert Social Investment Fund

CSIF seeks to invest in companies that:

o Deliver safe products and services in ways that sustain our natural
environment. For example, CSIF looks for companies that produce energy from
renewable resources, while avoiding consistent polluters.

o Manage with participation throughout the organization in defining and
achieving objectives. For example, CSIF looks for companies that offer
employee stock ownership or profit-sharing plans.

o Negotiate fairly with their workers, provide an environment supportive of
their wellness, do not discriminate on the basis of race, gender, religion,
age, disability, ethnic origin, or sexual orientation, do not consistently
violate regulations of the EEOC, and provide opportunities for women,
disadvantaged minorities, and others for whom equal opportunities have often
been denied. For example, CSIF considers both unionized and non-union firms
with good labor relations.

o Foster awareness of a commitment to human goals, such as creativity,
productivity, self-respect and responsibility, within the organization and the
world, and continually recreates a context within which these goals can be
realized. For example, CSIF looks for companies with an above average
commitment to community affairs and charitable giving.

CSIF will not invest in companies that the Advisor determines to be
significantly engaged in:

o Production, or the manufacture of equipment, to produce nuclear energy

o Business activities in support of repressive regimes

o Manufacture of weapon systems

o Manufacture of alcoholic beverages or tobacco products

o Operation of gambling casinos

With respect to U.S. government securities, CSIF invests primarily in debt
obligations issued or guaranteed by agencies or instrumentalities of the U.S.
Government whose purposes further or are compatible with CSIF's social
criteria, such as obligations of the Student Loan Marketing Association,
rather than general obligations of the U.S. Government, such as Treasury
securities.

<PAGE>

Calvert World Values International Equity Fund

The spirit of Calvert World Values International Equity Fund's social criteria
is similar to CSIF, but the application of the social analysis is
significantly different. International investing brings unique challenges in
terms of corporate disclosure, regulatory structures, environmental standards,
and differing national and cultural priorities. Due to these factors, the CWVF
social investment standards are less stringent than those of CSIF.

CWVF seeks to invest in companies that:

o Achieve excellence in environmental management. We select investments that
take positive steps toward preserving and enhancing our natural environment
through their operations and products. We avoid companies with poor
environmental records.

o Have positive labor practices. We consider the International Labor
Organization's basic conventions on worker rights as a guideline for our labor
criteria. We seek to invest in companies that hire and promote women and
ethnic minorities; respect the right to form unions; comply, at a minimum,
with domestic hour and wage laws; and provide good health and safety
standards. We avoid companies that demonstrate a pattern of engaging in
forced, compulsory, or child labor.

CWVF avoids investing in companies that:

o Contribute to human rights abuses in other countries 1

o Produce nuclear power or nuclear weapons, or have more than 10% of revenues
derived from the production or sale of weapons systems

o Derive more than 10% of revenues from the production of alcohol or tobacco
products, but actively seeks to invest in companies whose products or services
improve the quality of or access to health care, including public health and
preventative medicine

Calvert Capital Accumulation Fund
Calvert New Vision Small Cap Fund

The Funds carefully review company policies and behavior regarding social
issues important to quality of life such as:

         o environment
         o employee relations
         o product criteria
         o weapons systems
         o nuclear energy
         o human rights

Both Funds will avoid investing in companies that have:

o Significant or historical patterns of violating environmental regulations,
or otherwise have an egregious environmental record
o Significant or historical patterns of discrimination against employees on
the basis of race, gender, religion, age, disability or sexual
orientation, or that have major labor-management disputes
o Nuclear power plant operators and owners, or manufacturers of key components
in the nuclear power process
o Significantly engaged in weapons production( including weapons systems
contractors and major nuclear weapons systems
         contractors)
o Significantly involved in the manufacture of tobacco or alcohol products
o Products or offer services that, under proper use, are considered harmful

The Advisor will seek to review companies' overseas operations consistent with
the social criteria stated above.

While Capital Accumulation and New Vision may invest in companies that exhibit
positive social characteristics, they make no explicit claims to seek out
companies with such practices.

1 CWVF may invest in companies that operate in countries with poor human
rights records if we believe the companies are making a positive contribution.

High Social Impact Investments - CSIF Balanced, Bond and Equity, Calvert World
Values International Equity, Capital Accumulation and New Vision

High Social Impact Investments is a program that targets a percentage of the
Fund's assets (up to 1% for each of CSIF Balanced, CSIF Equity and CSIF Bond
and New Vision and up to 3% for each of CWVF International Equity and Capital
Accumulation) to directly support the growth of community-based organizations
for the purposes of promoting business creation, housing development, and
economic and social development of urban and rural communities. These types of
investments offer a rate of return below the then-prevailing market rate, and
are considered illiquid, unrated and below-investment grade. They also involve
a greater risk of default or price decline than investment grade securities.
However, they have a significant social return by making a tremendous
difference in our local communities. High Social Impact Investments are valued
under the direction and control of the Fund's Board.

The Funds have received an exemptive order to permit them to invest those
assets allocated for investment in high social impact investments through the
purchase of Community Investment Notes from the Calvert Social Investment
Foundation. The Calvert Social Investment Foundation is a non-profit
organization, legally distinct from Calvert Group, organized as a charitable
and educational foundation for the purpose of increasing public awareness and
knowledge of the concept of socially responsible investing. It has instituted
the Calvert Community Investments program to raise assets from individual and
institutional investors and then invest these assets directly in non-profit or
not-for-profit community development organizations and community development
banks that focus on low income housing, economic development and business
development in urban and rural communities.

Special Equities - CSIF Balanced and Calvert World Values International Equity

CSIF Balanced and CWVF International Equity each have a Special Equities
investment program that allows the Fund to promote especially promising
approaches to social goals through privately placed investments. The
investments are generally venture capital investments in small, untried
enterprises. The Special Equities Committee of each Fund identifies,
evaluates, and selects the Special Equities investments.  Special Equities
involve a high degree of risk-- they are subject to liquidity, information,
and if a debt investment, credit risk. Special Equities are valued under the
direction and control of the Fund's Board.

Advisory Fees

The following table shows the aggregate annual advisory fee paid to CAMCO by
each Fund for the most recent fiscal year as a percentage of that Fund's
average daily net assets .

     CSIF Balanced                                           0.62% 2, 5
     CSIF Managed Index                                      0.60% 3, 4
     CSIF Equity                                             0.56% 2, 5
     CSIF Bond                                               0.55% 1, 2
     CWVF International Equity                                  1.00% 2
     Capital Accumulation                                    0.79% 2, 5
     New Vision Small Cap                                       0.90% 2

1    CAMCO waived part of its advisory fee for CSIF Bond. The full contractual
rate CSIF Bond was obligated to pay CAMCO for fiscal year 1998 was 0.65%.
2    These advisory agreements are proposed to be changed by a vote of
shareholders in February 1999. If approved, the new advisory fee would be:
CSIF Balanced, 0.425%; CSIF Equity, 0.50%; CSIF Bond, 0.35%; CWVF
International Equity, 0.75%; Capital Accumulation, 0.65%; and New Vision Small
Cap, 0.75%. Note the advisory fee does not include the administrative services
fee, paid to the Advisor's affiliate. See the fee table of "Fees and Expenses"
for the combined advisory and administrative services fee shown as "Management
Fee."
3    CSIF Managed Index has not had a full year of operations. Its advisory
agreement provides for a fee of 0.60% of the Portfolio's first $500 million of
average daily net assets and 0.55% of any such assets over $500 million.
4    CSIF Managed Index has a recapture provision under which CAMCO may elect
to recapture from the Fund in a later year any fees CAMCO waives or expenses
it assumes, subject to certain limitations.
5    CSIF Balanced has a performance adjustment which could cause the fee to
be as high as 0.85% or as low as 0.55%, depending on the Fund's performance
relative to the relevant index (CAMCO: Lehman Aggregate Bond; NCM: Russell
3000; Brown: S&P 500). CSIF Equity has a performance adjustment which would
cause the fee to be as high as 0.90% or as low as 0.50%, depending on its
performance relative to the S&P 500 Index. Capital Accumulation has a
performance adjustment which could cause the fee to be as high as 0.85% or as
low as 0.75%, depending on the Fund's performance relative to the S&P 400
Midcap Index. These performance adjustments are proposed to be eliminated by a
vote of shareholders in February 1999.

A Word About the Year 2000 (Y2K) and Our Computer Systems

Like other mutual funds, CAMCO and its service providers use computer systems
for all aspects of our business -- processing shareholder and fund
transactions, fund accounting, executing trades, and pricing securities just
to name a few. Many current software programs cannot distinguish between the
year 2000 and the year 1900. This can cause problems with retirement plan
distributions, dividend payment software, transaction software, and numerous
other areas that could impact the Funds. Calvert Group has been reviewing all
of its computer systems for Y2K compliance. Although, at this time, there can
be no assurance that there will be no negative impact on the Funds, the
Advisor, the underwriter, transfer agent and custodian have advised the Funds
that they have been actively working on any necessary changes to their
computer systems to prepare for Y2K and expect that their systems, and those
of their outside service providers, will be adapted in time for that event.
For more information, please visit our website at www.calvertgroup.com.

HOW TO OPEN AN ACCOUNT

Complete and sign an application for each new account. Be sure to specify
Class I. All purchases must be made by bankwire in U.S. dollars. For more
information and wire instructions, call Calvert Group at 800-327-2109.

Minimum To Open an Account $1,000,000

IMPORTANT - HOW SHARES ARE PRICED
The price of shares is based on each Fund's net asset value ("NAV"). NAV is
computed by adding the value of a Fund's holdings plus other assets,
subtracting liabilities, and then dividing the result by the number of shares
outstanding. If a Fund has more than one class of shares, the NAV of each
class will be different, depending on the number of shares outstanding for
each class.

Portfolio securities and other assets are valued based on market quotations,
except that securities maturing within 60 days are valued at amortized cost.
If market quotations are not readily available, securities are valued by a
method that the Fund's Board of Trustees/Directors believes accurately
reflects fair value.

The NAV is calculated as of the close of each business day, which coincides
with the closing of the regular session of the New York Stock Exchange
("NYSE") (normally 4 p.m. ET). Each Fund is open for business each day the
NYSE is open. Please note that there are some federal holidays, however, such
as Columbus Day and Veteran's Day, when the NYSE is open and the Fund is open
but purchases cannot be made due to the closure of the banking system.

Some Funds hold securities that are primarily listed on foreign exchanges that
trade on days when the NYSE is closed. These Funds do not price shares on days
when the NYSE is closed, even if foreign markets may be open. As a result, the
value of the Fund's shares may change on days when you will not be able to buy
or sell your shares.

WHEN YOUR ACCOUNT WILL BE CREDITED
Your purchase will be processed at the next NAV calculated after your order is
received in good order. Each Fund reserves the right to suspend the offering
of shares for a period of time or to reject any specific purchase order. All
purchases will be confirmed and credited to your account in full and
fractional shares (rounded to the nearest 1/1000th of a share).

TELEPHONE TRANSACTIONS
You may purchase, redeem, or exchange shares and wire funds by telephone if
you have pre-authorized service instructions. You receive telephone privileges
automatically when you open your account unless you elect otherwise. For our
mutual protection, the Fund, the shareholder servicing agent and their

recording telephone calls to confirm instructions given by phone. A
confirmation statement is sent for most transactions; please review this
statement and verify the accuracy of your transaction immediately.

<PAGE>

EXCHANGES
Calvert Group offers a wide variety of investment options that includes common
stock funds, tax-exempt and corporate bond funds, and money market funds (call
your broker or Calvert representative for more information). We make it easy
for you to purchase shares in other Calvert funds if your investment goals
change.

Complete and sign an account application, taking care to register your new
account in the same name and taxpayer identification number as your existing
Calvert account(s). Exchange instructions may then be given by telephone if
telephone redemptions have been authorized and the shares are not in
certificate form.

Before you make an exchange, please note the following:
Each exchange represents the sale of shares of one Fund and the purchase of
shares of another. Therefore, you could realize a taxable gain or loss.

Shares may only be exchanged for Class I shares of another Calvert Fund.

Shareholders (and those managing multiple accounts) who make two purchases and
two exchange redemptions of shares of the same Fund during any six-month
period will be given written notice and may be prohibited from placing
additional investments. This policy does not prohibit a shareholder from
redeeming shares of any Fund, and does not apply to trades solely between
money market funds.

Each Fund reserves the right to terminate or modify the exchange privilege
with 60 days' written notice.

COMBINED GENERAL MAILINGS (Householding)
Multiple accounts with the same social security number will receive one
mailing per household of information such as prospectuses and semi-annual and
annual reports. You may request further grouping of accounts to receive fewer
mailings. Separate statements will be generated for each separate account and
will be mailed in one envelope for each combination above.

SPECIAL SERVICES AND CHARGES
Each Fund pays for shareholder services but not for special services that are
required by a few shareholders, such as a request for a historical transcript
of an account. You may be required to pay a fee for these special services.

MINIMUM ACCOUNT BALANCE
Please maintain a balance in each of your Fund accounts of at least $1,000,000
per Fund. If due to redemptions, the account falls below the minimum, your
account may be closed and the proceeds mailed to the address of record. You
will be given a notice that your account is below the minimum and will be
closed, or moved to Class A (at NAV) after 30 days if the balance is not
brought up to the required minimum amount.

DIVIDENDS, CAPITAL GAINS AND TAXES
Each Fund pays dividends from its net investment income as shown below. Net
investment income consists of interest income, net short-term capital gains,
if any, and dividends declared and on investments, less expenses.
Distributions of net short-term capital gains (treated as dividends for tax
purposes) and net long-term capital gains, if any, are normally paid once a
year; however, the Funds do not anticipate making any such distributions
unless available capital loss carryovers have been used or have expired.
Dividend and distribution payments will vary between classes.

     CSIF Bond                                    Paid monthly
     CSIF Balanced                              Paid quarterly
     CSIF Equity                                 Paid annually
     CSIF Managed Index                          Paid annually
     CWVF International Equity                   Paid annually
     Capital Accumulation                        Paid annually
     New Vision Small Cap                        Paid annually

<PAGE>

Dividend payment options
Dividends and any distributions are automatically reinvested in the same Fund
at NAV, unless you elect to have amounts of $10 or more paid to you by wire to
a predesignated bank account. Dividends and distributions from any Calvert
Group Fund may be automatically invested in an identically registered account
in any other Calvert Group Fund at NAV. If reinvested in the same account, new
shares will be purchased at NAV on the reinvestment date, which is generally 1
to 3 days prior to the payment date. You must notify the Funds in writing to
change your payment options.

Buying a Dividend
At the time of purchase, the share price of each class may reflect
undistributed income, capital gains or unrealized appreciation of securities.
Any income or capital gains from these amounts which are later distributed to
you are fully taxable. On the record date for a distribution, share value is
reduced by the amount of the distribution. If you buy shares just before the
record date ("buying a dividend") you will pay the full price for the shares
and then receive a portion of the price back as a taxable distribution.

Federal Taxes
In January, each Fund will mail you Form 1099-DIV indicating the federal tax
status of dividends and any capital gain distributions paid to you during the
past year. Generally, dividends and distributions are taxable in the year they
are paid. However, any dividends and distributions paid in January but
declared during the prior three months are taxable in the year declared.
Dividends and distributions are taxable to you regardless of whether they are
taken in cash or reinvested. Dividends, including short-term capital gains,
are taxable as ordinary income. Distributions from long-term capital gains are
taxable as long-term capital gains, regardless of how long you have owned
shares.

You may realize a capital gain or loss when you sell or exchange shares. This
capital gain or loss will be short- or long-term, depending on how long you
have owned the shares which were sold. In January, these Funds will mail you
Form 1099-B indicating the total amount of all sales, including exchanges. You
should keep your annual year-end account statements to determine the cost
(basis) of the shares to report on your tax returns.
 
Other Tax Information
In addition to federal taxes, you may be subject to state or local taxes on
your investment, depending on the laws in your area. You will be notified to
the extent, if any, that dividends reflect interest received from US
government securities. Such dividends may be exempt from certain state income
taxes.

Taxpayer Identification Number
If we do not have your correct Social Security or Taxpayer Identification
Number ("TIN") and a signed certified application or Form W-9, Federal law
requires us to withhold 31% of your reportable dividends, and possibly 31% of
certain redemptions. In addition, you may be subject to a fine by the Internal
Revenue Service. You will also be prohibited from opening another account by
exchange. If this TIN information is not received within 60 days after your
account is established, your account may be redeemed (closed) at the current
NAV on the date of redemption. Calvert Group reserves the right to reject any
new account or any purchase order for failure to supply a certified TIN.

HOW TO SELL SHARES

You may redeem all or a portion of your shares on any day your Fund is open
for business. Your shares will be redeemed at the next NAV calculated after
your redemption request is received and accepted. (The proceeds will normally
be sent to you on the next business day, but if making immediate payment could
adversely affect your Fund, it may take up to seven (7) days to make payment..
The Funds have the right to redeem shares in assets other than cash for
redemption amounts exceeding, in any 90-day period, $250,000 or 1% of the net
asset value of the affected Fund, whichever is less. When the NYSE is closed
(or when trading is restricted) for any reason other than its customary
weekend or holiday closings, or under any emergency circumstances as
determined by the Securities and Exchange Commission, redemptions may be
suspended or payment dates postponed.

Follow these suggestions to ensure timely processing of your redemption
request:

By Telephone - call 800-368-2745
You may redeem shares from your account by telephone and have your money wired
to an address or bank you have previously authorized. Class I redemptions must
be made by wire. Please note that there are some federal holidays, however,
such as Columbus Day and Veteran's Day, when the NYSE is open and the Fund is
open but redemptions cannot be made due to the closure of the banking system.

If you want the money to be wired to a bank not previously authorized, then a
voided bank check must be provided. To add instructions to wire to a
destination not previously established, or if you would like funds sent to a
different address or another person, your letter must be signature guaranteed.

FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the Funds'
financial performance for the past 5 years (or if shorter, the period of the
Fund's operations). Certain information reflects financial results for a
single share, by Fund and Class. The total returns in the table represent the
rate that an investor would have earned (or lost) on an investment in a Fund
(assuming reinvestment of all dividends and distributions), and does not
reflect any applicable front- or back-end sales charge. This information has
been audited by PricewaterhouseCoopers LLP whose report, along with a Fund's
financial statements, are included in the Fund's annual report, which is
available upon request.

                         INVESTMENT POLICIES AND RISKS
- --------------------------------------------------------------------------------

         Calvert  World  Values  Fund,  Inc.,  International  Equity  Fund  (the
"Fund") seeks to achieve a high total return  consistent with  reasonable  risk,
by  investing   primarily  in  a  globally   diversified   portfolio  of  equity
securities.  To the extent  possible,  investments are made in enterprises  that
make a significant  contribution  to our global  society  through their products
and services and through the way they do business.
         Under normal  circumstances,  the Fund will invest  primarily in equity
securities.  However,  the  Fund  may  invest  in any  other  type  of  security
including,  but  not  limited  to,  convertible  securities,  preferred  stocks,
bonds,  notes and other debt securities of companies,  (including  Euro-currency
instruments  and securities) or of any  international  agency (such as the Asian
Development  Bank  or   Inter-American   Development  Bank)  or  obligations  of
domestic  or  foreign  governments  and  their  political  subdivisions,  and in
foreign currency transactions.
         Under normal  circumstances,  the Fund will invest in the securities of
issuers  in many  different  countries,  other  than  the USA.  The  Fund  makes
investments  in  various  countries.   Under  exceptional   economic  or  market
conditions,  the Fund may invest  substantially all of its assets in only one or
two countries, or in US government obligations.
         In  determining  the  appropriate  distribution  of  investments  among
various  countries  and  geographic  regions,  the  Subadvisor  ordinarily  will
consider the following  factors:  prospects for relative  economic  growth among
foreign  countries;  expected levels of inflation;  relative price levels of the
various capital markets;  government policies  influencing  business conditions;
the outlook for currency  relationships  and the range of individual  investment
opportunities available to the global investor.

Foreign Securities
         Investments  in foreign  securities  may  present  risks not  typically
involved in  domestic  investments.  The Fund may  purchase  foreign  securities
directly,  on foreign  markets,  or those  represented  by  American  Depositary
Receipts   ("ADRs"),   or  other  receipts   evidencing   ownership  of  foreign
securities,  such as  International  Depositary  Receipts and Global  Depositary
Receipts.  ADRs are US  dollar-denominated  and traded in the US on exchanges or
over the  counter.  If the Fund invests in ADRs  rather than  directly in 
foreign issuers'  stock,  the Fund may possibly  avoid some currency and some  
liquidity risks.  The  information  available  for ADRs is subject to the more 
uniform and more  exacting  accounting,  auditing and financial  reporting
standards of the domestic market or exchange on which they are traded.
         Additional  costs may be  incurred  in  connection  with  international
investment  since  foreign   brokerage   commissions  and  the  custodial  costs
associated with maintaining  foreign  portfolio  securities are generally higher
than in the  United  States.  Fee  expense  may  also be  incurred  on  currency
exchanges  when the Fund  changes  investments  from one  country  to another or
converts foreign securities holdings into U.S. dollars.
         United States Government  policies have at times, in the past,  through
imposition of interest  equalization taxes and other  restrictions,  discouraged
certain  investments  abroad by United States  investors.  In addition,  foreign
countries may impose withholding and taxes on dividends and interest.
         Since  investments  in  securities  of  issuers  domiciled  in  foreign
countries  usually involve  currencies of the foreign  countries,  and since the
Fund may temporarily hold funds in foreign  currencies  during the completion of
investment  programs,  the value of the assets of the Fund as measured in United
States  dollars may be affected  favorably or  unfavorably by changes in foreign
currency exchange rates and exchange control  regulations.  For example,  if the
value of the foreign  currency in which a security is  denominated  increases or
declines  in  relation  to the  value  of the  U.S.  dollar,  the  value  of the
security in U.S.  dollars  will  increase or decline  correspondingly.  The Fund
will  conduct  its  foreign  currency  exchange  transactions  either  on a spot
(i.e.,  cash) basis at the spot rate prevailing in the foreign  exchange market,
or  through  entering  into  forward  contracts  to  purchase  or  sell  foreign
currencies.  It may also use foreign currency options and futures.  See below. A
forward foreign currency  contract  involves an obligation to purchase or sell a
specific  currency at a future  date which may be any fixed  number of days from
the date of the  contract  agreed  upon by the  parties,  at a price  set at the
time of the  contract.  These  contracts  are  traded  in the  interbank  market
conducted  directly between currency traders (usually large,  commercial  banks)
and their  customers.  A forward  foreign  currency  contract  generally  has no
deposit requirement, and no commissions are charged at any stage for trades.
         The Fund may enter into  forward  foreign  currency  contracts  for two
reasons.  First,  the Fund may desire to preserve the United States dollar price
of a security  when it enters  into a  contract  for the  purchase  or sale of a
security  denominated  in a foreign  currency.  The Fund may be able to  protect
itself  against  possible  losses  resulting  from  changes in the  relationship
between  the United  States  dollar  and  foreign  currencies  during the period
between  the  date  the  security  is  purchased  or sold  and the date on which
payment  is made  or  received  by  entering  into a  forward  contract  for the
purchase or sale,  for a fixed  amount of dollars,  of the amount of the foreign
currency involved in the underlying security transactions.
         Second,  when the Advisor or  Subadvisor  believes that the currency of
a  particular  foreign  country  may suffer a  substantial  decline  against the
United States dollar,  the Fund enters into a forward foreign currency  contract
to  sell,  for a fixed  amount  of  dollars,  the  amount  of  foreign  currency
approximating the value of some or all of the Fund's  securities  denominated in
such foreign  currency.  The precise  matching of the forward  foreign  currency
contract  amounts  and the  value of the  Fund's  securities  involved  will not
generally be possible  since the future value of the  securities  will change as
a  consequence  of market  movements  between the date the  forward  contract is
entered into and the date it matures.  The  projection  of  short-term  currency
market  movement is difficult,  and the successful  execution of this short-term
hedging  strategy is uncertain.  Although  forward  foreign  currency  contracts
tend to  minimize  the risk of loss due to a decline  in the value of the hedged
currency,  at the same time they tend to limit any  potential  gain which  might
result should the value of such currency  increase.  The Fund does not intend to
enter  into such  forward  contracts  under  this  circumstance  on a regular or
continuous basis.
         Eurocurrency  Conversion Risk.  European  countries that are members of
the  European  Monetary  Union have agreed to use a common  currency  unit,  the
"euro,"  beginning  in  1999.  Currently,  each of these  countries  has its own
currency  unit.  Although  the  Advisor and  Subadvisor  do not  anticipate  any
problems  in  conversion  from the old  currencies  to the  euro,  there  may be
issues  involved in settlement,  valuation,  and numerous other areas that could
impact the Fund.  Calvert has been  reviewing  all of its  computer  systems for
Eurocurrency  conversion  compliance.  There can be no assurance that there will
be no  negative  impact  on the  Fund,  however,  the  Advisor,  Subadvisor  and
custodian  have  advised  the Fund that they have been  actively  working on any
necessary  changes to their computer systems to prepare for the conversion,  and
expect that their systems,  and those of their outside service  providers,  will
be adapted in time for that event.

TEMPORARY DEFENSIVE POSITIONS
         For  temporary  defensive  purposes  -  which  may  include  a lack  of
adequate  purchase  candidates or an unfavorable  market  environment - the Fund
may invest in cash or cash  equivalents.  Cash equivalents  include  instruments
such  as,  but  not  limited  to,  U.S.   government  and  agency   obligations,
certificates of deposit,  banker's acceptances,  time deposits commercial paper,
short-term corporate debt securities, and repurchase agreements.

Repurchase Agreements
         The  Fund  may  purchase   debt   securities   subject  to   repurchase
agreements,  which are  arrangements  under which the Fund buys a security,  and
the seller  simultaneously  agrees to  repurchase  the  security  at a specified
time and  price  reflecting  a market  rate of  interest.  The Fund  engages  in
repurchase  agreements  in order to earn a higher  rate of return  than it could
earn  simply  by  investing  in  the  obligation  which  is the  subject  of the
repurchase agreement.  Repurchase agreements are not, however,  without risk. In
the  event  of the  bankruptcy  of a  seller  during  the  term of a  repurchase
agreement,  a legal  question  exists as to whether the Fund would be deemed the
owner of the  underlying  security  or would be deemed  only to have a  security
interest  in and  lien  upon  such  security.  The  Fund  will  only  engage  in
repurchase  agreements with recognized  securities  dealers and banks determined
to  present  minimal  credit  risk  by  the  Advisor  under  the  direction  and
supervision  of the Fund's Board of Directors.  In addition,  the Fund will
only engage in repurchase  agreements reasonably designed to secure fully during
the term of the agreement the seller's  obligation to repurchase  the underlying
security and will monitor the market value of the underlying security during the
term of the agreement.  If the value of the underlying  security declines and is
not at  least  equal  to the  repurchase  price  due the  Fund  pursuant  to the
agreement,  the Fund will require the seller to pledge additional  securities or
cash to secure the seller's obligations pursuant to the agreement. If the seller
defaults  on its  obligation  to  repurchase  and the  value  of the  underlying
security  declines,  the Fund may incur a loss and may incur expenses in selling
the underlying  security.  Repurchase  agreements are always for periods of less
than one year.  Repurchase  agreements  not  terminable  within  seven  days are
considered illiquid.
<PAGE>

Reverse Repurchase Agreements
         The Fund may also  engage in  reverse  repurchase  agreements.  Under a
reverse  repurchase   agreement,   the  Fund  sells  securities  to  a  bank  or
securities  dealer and agrees to repurchase  those securities from such party at
an agreed upon date and price  reflecting  a market rate of  interest.  The Fund
invests the proceeds from each reverse  repurchase  agreement in  obligations in
which it is  authorized  to  invest.  The Fund  intends  to enter into a reverse
repurchase  agreement  only  when  the  interest  income  provided  for  in  the
obligation  in which the Fund  invests  the  proceeds  is expected to exceed the
amount the Fund will pay in interest to the other  party to the  agreement  plus
all costs associated with the  transactions.  The Fund does not intend to borrow
for leverage  purposes.  The Fund will only be permitted to pledge assets to the
extent necessary to secure borrowings and reverse repurchase agreements.
         During the time a reverse  repurchase  agreement  is  outstanding,  the
Fund will  maintain in a segregated  custodial  account an amount of cash,  U.S.
Government  securities or other liquid,  high-quality  debt securities  equal in
value to the  repurchase  price.  The Fund  will  mark to  market  the  value of
assets held in the segregated  account,  and will place additional assets in the
account  whenever  the  total  value  of the  account  falls  below  the  amount
required under applicable regulations.
         The Fund's  use of  reverse  repurchase  agreements  involves  the risk
that the other party to the  agreements  could become  subject to  bankruptcy or
liquidation  proceedings  during the period the agreements are  outstanding.  In
such event,  the Fund may not be able to repurchase  the  securities it has sold
to that other party.  Under those  circumstances,  if at the  expiration  of the
agreement  such  securities  are of greater value than the proceeds  obtained by
the Fund  under the  agreements,  the Fund may have been  better  off had it not
entered  into  the  agreement.   However,  the  Fund  will  enter  into  reverse
repurchase  agreements  only with banks and dealers  which the Advisor  believes
present  minimal  credit risks under  guidelines  adopted by the Fund's Board of
Directors.  In  addition,  the Fund bears the risk that the market  value of the
securities  it sold may  decline  below the  agreed-upon  repurchase  price,  in
which case the dealer may request the Fund to post additional collateral.

Non-Investment Grade Debt Securities
         Non-investment   grade  debt   securities   are  lower   quality   debt
securities  (generally  those  rated  BB or  lower  by  S&P  or Ba or  lower  by
Moody's,  known  as  "junk  bonds").  These  securities  have  moderate  to poor
protection   of   principal   and  interest   payments   and  have   speculative
characteristics.  (See  Appendix  for  a  description  of  the  ratings.)  These
securities  involve  greater risk of default or price declines due to changes in
the issuer's  creditworthiness than  investment-grade  debt securities.  Because
the market for  lower-rated  securities  may be thinner and less active than for
higher-rated  securities,  there  may  be  market  price  volatility  for  these
securities and limited  liquidity in the resale market.  Market prices for these
securities may decline  significantly in periods of general economic  difficulty
or  rising  interest  rates.  Unrated  debt  securities  may fall into the lower
quality  category.  Unrated  securities  usually are not  attractive  to as many
buyers as rated securities are, which may make them less marketable.
         The quality  limitation  set forth in the Fund's  investment  policy is
determined  immediately  after  the  Fund's  acquisition  of a  given  security.
Accordingly,   any  later  change  in  ratings  will  not  be  considered   when
determining whether an investment complies with the Fund's investment policy.
         When  purchasing  high-yielding  securities,   rated  or  unrated,  the
Advisors  prepare  their own  careful  credit  analysis  to attempt to  identify
those issuers whose financial  condition is adequate to meet future  obligations
or is expected to be adequate in the future.  Through Fund  diversification  and
credit  analysis,  investment  risk can be  reduced,  although  there  can be no
assurance that losses will not occur.

INDUSTRY CONCENTRATION (BOND ONLY)
         Funds  that may  concentrate  (invest  25% or more of their  assets) in
one or more  industries are more  susceptible to market changes in that industry
sector.  For  example,  a downturn in the  technology  sector will have a bigger
impact on a Fund that chose to concentrate  in the  technology  industry then on
a Fund that did not concentrate.

DERIVATIVES
         The Fund  can use  various  techniques  to  increase  or  decrease  its
exposure to changing  security  prices,  interest  rates,  or other factors that
affect security  values.  These techniques may involve  derivative  transactions
such as buying and selling  options and futures  contracts and leveraged  notes,
entering into swap agreements,  and purchasing indexed securities.  The Fund can
use these practices  either as substitution or as protection  against an adverse
move in the Fund to adjust the risk and return  characteristics  of the Fund. If
the Advisor and/or Subadvisor  judges market  conditions  incorrectly or employs
a strategy that does not  correlate  well with a Fund's  investments,  or if the
counterparty to the transaction  does not perform as promised,  these techniques
could result in a loss.  These  techniques may increase the volatility of a Fund
and may involve a small  investment  of cash  relative to the  magnitude  of the
risk assumed. Derivatives are often illiquid.

Options and Futures Contracts
         The Fund may,  in  pursuit  of its  respective  investment  objectives,
purchase  put and call  options  and  engage  in the  writing  of  covered  call
options  and  secured put  options on  securities  which meet the Fund's  social
criteria,  and employ a variety of other  investment  techniques.  Specifically,
the  Fund may also  engage  in the  purchase  and  sale of  stock  index  future
contracts,   foreign   currency   futures   contracts,   interest  rate  futures
contracts, and options on such futures, as described more fully below.
         The Fund may  engage in such  transactions  only to hedge the  existing
positions.  It  will  not  engage  in such  transactions  for  the  purposes  of
speculation or leverage.  Such investment  policies and techniques may involve a
greater  degree of risk than  those  inherent  in more  conservative  investment
approaches.
         The  Fund  may  write  "covered  options"  on  securities  in  standard
contracts  traded on  national  securities  exchanges.  The Fund may write  such
options in order to receive the  premiums  from  options that expire and to seek
net gains from closing purchase transactions with respect to such options.

Put and Call Options.  The Fund may purchase put and call  options,  in standard
contracts  traded on national  securities  exchanges,  on  securities of issuers
which meet the Fund's  social  criteria.  The Fund will  purchase  such  options
only to hedge against  changes in the value of securities  the Fund hold and not
for the purposes of speculation  or leverage.  By buying a put, the Fund has the
right to sell the  security at the  exercise  price,  thus  limiting its risk of
loss  through  a  decline  in the  market  value of the  security  until the put
expires.  The  amount  of any  appreciation  in  the  value  of  the  underlying
security  will be  partially  offset by the amount of the  premium  paid for the
put option and any related  transaction  costs.  Prior to its expiration,  a put
option  may be sold in a closing  sale  transaction  and any profit or loss from
the sale will  depend on whether  the amount  received  is more or less than the
premium paid for the put option plus the related transaction costs.
         The Fund  may  purchase  call  options  on  securities  which  they may
intend  to  purchase   and  which  meet  the  Fund's   social   criteria.   Such
transactions  may be  entered  into in order to limit the risk of a  substantial
increase  in the  market  price  of the  security  which  the  Fund  intends  to
purchase.  Prior to its expiration,  a call option may be sold in a closing sale
transaction.  Any  profit or loss from such a sale will  depend on  whether  the
amount  received is more or less than the premium  paid for the call option plus
the related transaction costs.

Covered  Options.  The Fund may write  only  covered  options on equity and debt
securities in standard contracts traded on national securities  exchanges.  This
means that,  in the case of call  options,  so long as the Fund is  obligated as
the writer of a call option,  the Fund will own the underlying  security subject
to the  option  and,  in the case of put  options,  the Fund will,  through  its
custodian,  deposit and maintain  either cash or securities  with a market value
equal to or greater than the exercise price of the option.
         When the  Fund  writes a  covered  call  option,  the  Fund  gives  the
purchaser  the right to purchase  the  security at the call option  price at any
time  during  the life of the  option.  As the  writer of the  option,  the Fund
receives  a  premium,   less  a  commission,   and  in  exchange   foregoes  the
opportunity  to profit  from any  increase in the market  value of the  security
exceeding  the call option price.  The premium  serves to mitigate the effect of
any  depreciation  in the market  value of the  security.  Writing  covered call
options  can  increase  the income of the Fund and thus  reduce  declines in the
net asset  value per share of the Fund if  securities  covered  by such  options
decline  in value.  Exercise  of a call  option by the  purchaser  however  will
cause the Fund to forego future  appreciation  of the securities  covered by the
option.
         When the Fund  writes a covered  put  option,  it will gain a profit in
the  amount  of the  premium,  less a  commission,  so long as the  price of the
underlying  security  remains  above  the  exercise  price.  However,  the  Fund
remains  obligated to purchase  the  underlying  security  from the buyer of the
put  option  (usually  in the event the price of the  security  falls  below the
exercise  price)  at any time  during  the  option  period.  If the price of the
underlying  security  falls  below the  exercise  price,  the Fund may realize a
loss in the amount of the  difference  between the  exercise  price and the sale
price of the security, less the premium received.
         The Fund  may  purchase  securities  which  may be  covered  with  call
options  solely on the basis of  considerations  consistent  with the investment
objectives  and policies of the Fund. The Fund's  turnover may increase  through
the exercise of a call  option;  this will  generally  occur if the market value
of a "covered"  security  increases  and the Fund has not entered into a closing
purchase transaction.
         Risks  Related  to  Options  Transactions.  The Fund can  close out its
respective  positions  in  exchange-traded  options  only on an  exchange  which
provides  a  secondary  market  in such  options.  Although  the Fund  intend to
acquire  and  write  only  such  exchange-traded  options  for  which an  active
secondary  market  appears  to  exist,  there  can be no  assurance  that such a
market will exist for any particular  option  contract at any  particular  time.
This  might  prevent  the Fund from  closing an options  position,  which  could
impair the Fund's  ability to hedge  effectively.  The  inability to close out a
call  position may have an adverse  effect on liquidity  because the Fund may be
required to hold the  securities  underlying the option until the option expires
or is exercised.

Over-the-Counter  ("OTC")  Options.  OTC  options  differ  from  exchange-traded
options in several respects.  They are transacted  directly with dealers and not
with a  clearing  corporation,  and  there is a risk of  non-performance  by the
dealer.  However,  the premium is paid in advance by the dealer. OTC options are
available for a greater variety of securities and foreign  currencies,  and in a
wider  range of  expiration  dates  and  exercise  prices  than  exchange-traded
options.  Since there is no exchange,  pricing is normally  done by reference to
information  from a market maker,  which  information is carefully  monitored or
caused to be monitored by the Subadvisor and verified in appropriate cases.
         A  writer  or  purchaser  of a put or  call  option  can  terminate  it
voluntarily  only by  entering  into a closing  transaction.  In the case of OTC
options,  there can be no assurance that a continuous  liquid  secondary  market
will exist for any  particular  option at any specific time.  Consequently,  the
Fund may be able to  realize  the value of an OTC option it has  purchased  only
by  exercising it or entering  into a closing sale  transaction  with the dealer
that issued it.  Similarly,  when the Fund writes an OTC  option,  it  generally
can  close out that  option  prior to its  expiration  only by  entering  into a
closing  purchase  transaction  with the dealer to which it originally wrote the
option.  If a covered call option writer  cannot  effect a closing  transaction,
it cannot  sell the  underlying  security or foreign  currency  until the option
expires  or the option is  exercised.  Therefore,  the  writer of a covered  OTC
call  option  may not be able to sell an  underlying  security  even  though  it
might  otherwise be  advantageous  to do so.  Likewise,  the writer of a secured
OTC put  option may be unable to sell the  securities  pledged to secure the put
for  other  investment   purposes  while  it  is  obligated  as  a  put  writer.
Similarly,  a  purchaser  of an OTC  put or  call  option  might  also  find  it
difficult  to  terminate  its  position  on a timely  basis in the  absence of a
secondary market.
         The Fund  understands  the position of the staff of the  Securities and
Exchange  Commission  (the  "SEC")  to be that  purchased  OTC  options  and the
assets used as "cover" for written  OTC  options are  illiquid  securities.  The
Fund has adopted  procedures  for engaging in OTC options  transactions  for the
purpose of reducing any potential  adverse effect of such  transactions upon the
liquidity of the Fund.

Futures  Transactions.  The Fund may purchase and sell  futures  contracts,  but
only when,  in the  judgment  of the  Advisor,  such a position  acts as a hedge
against market changes which would  adversely  affect the securities held by the
Fund.  These  futures  contracts  may  include,  but are not limited to,  market
index  futures  contracts  and  futures  contracts  based  on  U.S.   Government
obligations.
         A futures  contract  is an  agreement  between  two  parties to buy and
sell a  security  on a future  date  which has the  effect of  establishing  the
current  price for the  security.  Although  futures  contracts  by their  terms
require  actual  delivery  and  acceptance  of  securities,  in most  cases  the
contracts  are  closed  out before the  settlement  date  without  the making or
taking of delivery  of  securities.  Upon buying or selling a futures  contract,
the Fund  deposits  initial  margin with its  custodian,  and  thereafter  daily
payments  of  maintenance  margin  are made to and from  the  executing  broker.
Payments  of  maintenance  margin  reflect  changes in the value of the  futures
contract,  with the Fund being  obligated  to make such  payments if its futures
position  becomes less  valuable  and  entitled to receive such  payments if its
positions become more valuable.
         The  Fund  may  only  invest  in  futures   contracts  to  hedge  their
respective  existing  investment  positions  and  not  for  income  enhancement,
speculation or leverage purposes.  Although some of the securities  underlying a
futures contract may not necessarily  meet the Fund's social criteria,  any such
hedge  position  taken  by the  Fund  will not  constitute  a  direct  ownership
interest in the underlying securities.
         Futures   contracts   are   designed  by  boards  of  trade  which  are
designated  "contracts  markets" by the  Commodity  Futures  Trading  Commission
("CFTC").  As series of a registered  investment  company,  the Fund is eligible
for exclusion from the CFTC's  definition of "commodity pool operator,"  meaning
that the  Fund may  invest  in  futures  contracts  under  specified  conditions
without  registering  with  the  CFTC.  Futures  contracts  trade  on  contracts
markets  in a  manner  that is  similar  to the way a  stock  trades  on a stock
exchange  and  the  boards  of  trade,  through  their  clearing   corporations,
guarantee performance of the contracts.

Options  on  Futures  Contracts.  The Fund may  purchase  and  write put or call
options  and sell call  options  on  futures  contracts  in which the Fund could
otherwise  invest  and which are  traded on a U.S.  exchange  or board of trade.
The Fund may also enter into closing  transactions  with respect to such options
to terminate an existing  position;  that is, to sell a put option already owned
and to buy a call option to close a position  where the Fund has already  sold a
corresponding call option.
         The Fund may only  invest in  options  on  futures  contracts  to hedge
their respective existing  investment  positions and not for income enhancement,
speculation or leverage  purposes.  Although some of the  securities  underlying
the futures  contract  underlying the option may not necessarily meet the Fund's
social  criteria,  any such hedge position taken by the Fund will not constitute
a direct ownership interest in the underlying securities.
         An option on a futures  contract  gives the  purchaser  the  right,  in
return for the premium paid, to assume a position in a futures  contract-a  long
position  if the  option  is a call  and a short  position  if the  option  is a
put-at a specified  exercise  price at any time during the period of the option.
The Fund will pay a premium for such options  purchased or sold.  In  connection
with such options  bought or sold,  the Fund will make initial  margin  deposits
and make or receive  maintenance  margin  payments which reflect  changes in the
market  value  of such  options.  This  arrangement  is  similar  to the  margin
arrangements applicable to futures contracts described above.

Put  Options  on  Futures  Contracts.  The  purchase  of put  options on futures
contracts is analogous to the sale of futures  contracts  and is used to protect
the Fund  against  the risk of  declining  prices.  The  Fund may  purchase  put
options and sell put  options on futures  contracts  that are  already  owned by
the Fund.  The Fund will only  engage in the  purchase  of put  options  and the
sale of covered put options on market index futures for hedging purposes.

Call  Options  on  Futures  Contracts.  The  sale of  call  options  on  futures
contracts is analogous to the sale of futures  contracts  and is used to protect
the Fund against the risk of declining  prices.  The purchase of call options on
futures contracts is analogous to the purchase of a futures  contract.  The Fund
may only buy call  options  to close an  existing  position  where  the Fund has
already sold a  corresponding  call option,  or for a cash hedge.  The Fund will
only  engage in the sale of call  options and the  purchase  of call  options to
cover for hedging purposes.

Writing  Call  Options  on Futures  Contracts.  The  writing of call  options on
futures  contracts  constitutes a partial hedge against  declining prices of the
securities  deliverable  upon exercise of the futures  contract.  If the futures
contract price at expiration is below the exercise  price,  the Fund will retain
the full amount of the option  premium  which  provides a partial  hedge against
any decline that may have occurred in the Fund's securities holdings.

Risks of Options and Futures  Contracts.  If the Fund has sold  futures or takes
options  positions to hedge  against  decline in the market and the market later
advances,  the Fund may suffer a loss on the futures  contracts or options which
it  would  not  have  experienced  if it had  not  hedged.  Correlation  is also
imperfect  between  movements in the prices of futures  contracts  and movements
in prices of the securities  which are the subject of the hedge.  Thus the price
of the  futures  contract or option may move more than or less than the price of
the  securities  being hedged.  Where the Fund has sold futures or taken options
positions  to hedge  against  decline in the market,  the market may advance and
the  value  of the  securities  held in the Fund may  decline.  If this  were to
occur,  the Fund might lose money on the futures  contracts  or options and also
experience a decline in the value of its securities.
         The Fund can close out futures  positions  only on an exchange or board
of trade which  provides a secondary  market in such futures.  Although the Fund
intend  to  purchase  or sell only such  futures  for which an active  secondary
market  appears  to exist,  there can be no  assurance  that such a market  will
exist for any particular  futures  contract at any particular  time.  This might
prevent the Fund from closing a futures  position,  which could require the Fund
to make  daily  cash  payments  with  respect  to its  position  in the event of
adverse price movements.
         Options on futures  transactions  bear  several  risks apart from those
inherent  in options  transactions  generally.  The Fund's  ability to close out
its options  positions in futures  contracts  will depend upon whether an active
secondary  market for such options  develops and is in existence at the time the
Fund seek to close its  positions.  There can be no assurance that such a market
will  develop or exist.  Therefore,  the Fund might be required to exercise  the
options to realize any profit.

Foreign Currency  Transactions.  Forward Foreign Currency Exchange Contracts.  A
forward foreign currency  exchange  contract  involves an obligation to purchase
or sell a specific  currency at a future date,  which may be any fixed number of
days  ("Term")  from the date of the contract  agreed upon by the parties,  at a
price set at the time of the  contract.  These  contracts  are  traded  directly
between currency traders (usually large commercial banks) and their customers.
         The Fund will not enter into such  forward  contracts or maintain a net
exposure in such  contracts  where it would be obligated to deliver an amount of
foreign  currency in excess of the value of its portfolio  securities  and other
assets  denominated  in  that  currency.  The  Subadvisor  believes  that  it is
important to have the  flexibility to enter into such forward  contracts when it
determines that to do so is in the Fund's best interests.
         Foreign  Currency  Options.  A foreign  currency  option  provides  the
option buyer with the right to buy or sell a stated  amount of foreign  currency
at the exercise price at a specified  date or during the option  period.  A call
option gives its owner the right,  but not the obligation,  to buy the currency,
while a put option gives its owner the right,  but not the  obligation,  to sell
the currency.  The option  seller  (writer) is obligated to fulfill the terms of
the option sold if it is  exercised.  However,  either seller or buyer may close
its  position  during  the  option  period  for such  options  any time prior to
expiration.
         A  call  rises  in  value  if  the  underlying  currency   appreciates.
Conversely,  a put rises in value if the underlying currency depreciates.  While
purchasing  a foreign  currency  option can protect the Fund  against an adverse
movement  in the value of a foreign  currency,  it does not limit the gain which
might  result  from a  favorable  movement  in the value of such  currency.  For
example,  if the Fund was  holding  securities  denominated  in an  appreciating
foreign  currency and had  purchased a foreign  currency put to hedge  against a
decline in the value of the  currency,  it would not have to  exercise  its put.
Similarly,  if the Fund had  entered  into a  contract  to  purchase  a security
denominated in a foreign  currency and had purchased a foreign  currency call to
hedge  against a rise in the value of the  currency but instead the currency had
depreciated  in value between the date of purchase and the  settlement  date, it
would not have to  exercise  its call but could  acquire in the spot  market the
amount of foreign currency needed for settlement.
         Foreign  Currency  Futures  Transactions.  The  Fund  may  use  foreign
currency futures  contracts and options on such futures  contracts.  Through the
purchase or sale of such  contracts,  it may be able to achieve many of the same
objectives  attainable  through the use of foreign currency  forward  contracts,
but more effectively and possibly at a lower cost.
         Unlike forward foreign currency  exchange  contracts,  foreign currency
futures  contracts  and  options  on  foreign  currency  futures  contracts  are
standardized  as to  amount  and  delivery  period  and are  traded on boards of
trade and  commodities  exchanges.  It is  anticipated  that such  contracts may
provide  greater   liquidity  and  lower  cost  than  forward  foreign  currency
exchange contracts.
         The value of the Fund's  assets as  measured in United  States  dollars
may be  affected  favorably  or  unfavorably  by  changes  in  foreign  currency
exchange rates and exchange  control  regulations,  and the Fund may incur costs
in  connection  with  conversions  between  various  currencies.  The Fund  will
conduct  its  foreign  currency  exchange  transactions  either on a spot (i.e.,
cash)  basis  at the spot  rate  prevailing  in the  foreign  currency  exchange
market, or through forward contracts to purchase or sell foreign  currencies.  A
forward foreign currency  exchange  contract  involves an obligation to purchase
or sell a specific  currency at a future date,  which may be any fixed number of
days from the date of the contract  agreed upon by the  parties,  at a price set
at the  time of the  contract.  These  contracts  are  traded  directly  between
currency traders (usually large commercial banks) and their customers.
         When the Fund  enters  into a contract  for the  purchase  or sale of a
security  denominated  in a  foreign  currency,  it may  want to  establish  the
United  States  dollar cost or proceeds,  as the case may be. By entering into a
forward  contract  in United  States  dollars  for the  purchase  or sale of the
amount of foreign  currency  involved in the  underlying  security  transaction,
the Fund is able to protect  itself  against a possible  loss between  trade and
settlement  dates resulting from an adverse change in the  relationship  between
the United  States  dollar and such  foreign  currency.  However,  this tends to
limit  potential  gains  which  might  result  from a  positive  change  in such
currency  relationships.  The Fund may also hedge its foreign currency  exchange
rate risk by engaging in currency financial futures and options transactions.
         When the  Advisor or the  Subadvisor  believes  that the  currency of a
particular  foreign country may suffer a substantial  decline against the United
States  dollar,  it may  enter  into a  forward  contract  to sell an  amount of
foreign  currency  approximating  the  value  of  some  or  all  of  the  Fund's
portfolio  securities  denominated in such foreign currency.  The forecasting of
short-term  currency market  movement is extremely  difficult and whether such a
short-term hedging strategy will be successful is highly uncertain.
         It is  impossible  to  forecast  with  precision  the market  values of
portfolio  securities at the  expiration of a contract.  Accordingly,  it may be
necessary for the Fund to purchase  additional  currency on the spot market (and
bear the expense of such  purchase)  if the market value of the security is less
than the amount of foreign  currency  the Fund is  obligated  to deliver  when a
decision  is made  to  sell  the  security  and  make  delivery  of the  foreign
currency in settlement of a forward  contract.  Conversely,  it may be necessary
to sell on the spot market some of the foreign  currency  received upon the sale
of the  portfolio  security  if its market  value  exceeds the amount of foreign
currency the Fund is obligated to deliver.
         If  the  Fund  retains  the security  and  engages  in  an
offsetting  transaction,  it will incur a gain or a loss (as described below) to
the extent  that there has been  movement  in forward  contract  prices.  If the
Fund engages in an  offsetting  transaction,  it may  subsequently  enter into a
new  forward  contract  to sell the  foreign  currency.  Should  forward  prices
decline  during the period  between the Fund  entering  into a forward  contract
for the sale of a foreign  currency  and the date it enters  into an  offsetting
contract for the purchase of the foreign  currency,  it would  realize  gains to
the extent the price of the  currency  it has agreed to sell  exceeds  the price
of the currency it has agreed to purchase.  Should forward prices increase,  the
Fund would  suffer a loss to the extent the price of the  currency it has agreed
to purchase  exceeds the price of the  currency it has agreed to sell.  Although
such  contracts  tend to minimize the risk of loss due to a decline in the value
of the hedged  currency,  they also tend to limit any potential gain which might
result  should  the  value  of such  currency  increase.  The  Fund  may have to
convert its  holdings of foreign  currencies  into United  States  dollars  from
time  to  time.  Although  foreign  exchange  dealers  do not  charge  a fee for
conversion,  they do realize a profit  based on the  difference  (the  "spread")
between the prices at which they are buying and selling various currencies.

LENDING FUND SECURITIES
         The  Fund  may  lend its  securities  to  member  firms of the New York
Stock  Exchange  and  commercial  banks with  assets of one  billion  dollars or
more,  provided  the value of the  securities  loaned will not exceed 33 1/3% of
assets.  Any such  loans  must be  secured  continuously  in the form of cash or
cash  equivalents  such as US Treasury bills.  The amount of the collateral must
on a current  basis equal or exceed the market  value of the loaned  securities,
and the Fund must be able to terminate  such loans upon notice at any time.  The
Fund  will  exercise  its  right  to  terminate  a  securities  loan in order to
preserve its right to vote upon matters of importance  affecting  holders of the
securities.
         The  advantage of such loans is that the Fund  continues to receive the
equivalent  of the  interest  earned or  dividends  paid by the  issuers  on the
loaned  securities  while  at the  same  time  earning  interest  on the cash or
equivalent  collateral  which may be  invested  in  accordance  with the  Fund's
investment objective, policies and restrictions.
         Securities  loans  are  usually  made  to   broker-dealers   and  other
financial  institutions  to facilitate  their  delivery of such  securities.  As
with any  extension  of  credit,  there  may be risks of delay in  recovery  and
possibly  loss of rights in the loaned  securities  should the  borrower  of the
loaned  securities fail  financially.  However,  the Fund will make loans of its
securities  only to those firms the  Advisor or  Subadvisor  deems  creditworthy
and only on terms the  Advisor  believes  should  compensate  for such risk.  On
termination  of the loan,  the borrower is obligated to return the securities to
the Fund.  The Fund will  recognize  any gain or loss in the market value of the
securities  during the loan period.  The Fund may pay reasonable  custodial fees
in connection with the loan.

                            INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------

         Shareholders  of the Fund are  currently  voting on various  changes to
the Fund,  pursuant  to a proxy  statement  mailed in early  January,  1999.  If
approved at the  special  meeting of  shareholders  on February  24,  1999,  the
revised fundamental investment restrictions will be as follows:

Fundamental Investment Restrictions
         The   Fund   has   adopted   the   following   fundamental   investment
restrictions.  These restrictions  cannot be changed without the approval of the
holders of a majority of the outstanding shares of the Fund.

         (1) The Fund may not make  any  investment  inconsistent  with
         its  classification as a diversified  investment company under
         the 1940 Act.
         (2)  The  Fund  may not  concentrate  its  investments  in the
         securities  of issuers  primarily  engaged  in any  particular
         industry  (other than  securities  issued or guaranteed by the
         U.S.  Government  or its  agencies  or  instrumentalities  and
         repurchase agreements secured thereby).
         (3) The  Fund  may  not  issue  senior  securities  or  borrow
         money,  except from banks for temporary or emergency  purposes
         and then  only in an  amount up to 33 1/3% of the value of its
         total  assets or as  permitted  by law and except by  engaging
         in reverse repurchase  agreements,  where allowed. In order to
         secure  any  permitted   borrowings  and  reverse   repurchase
         agreements under this section,  the Fund may pledge,  mortgage
         or hypothecate its assets.
         (4) The  Fund  may not  underwrite  the  securities  of  other
         issuers,  except as allowed  by law or to the extent  that the
         purchase of  obligations  in  accordance  with its  investment
         objective and policies,  either  directly from the issuer,  or
         from  an  underwriter   for  an  issuer,   may  be  deemed  an
         underwriting.
         (5) The Fund may not invest  directly in  commodities  or real
         estate,  although  it  may  invest  in  securities  which  are
         secured  by  real   estate  or  real  estate   mortgages   and
         securities  of issuers  which  invest or deal in  commodities,
         commodity futures, real estate or real estate mortgages.
         (6) The  Fund may not  make  loans,  other  than  through  the
         purchase   of  money   market   instruments   and   repurchase
         agreements  or by the purchase of bonds,  debentures  or other
         debt  securities,  or as permitted by law. The purchase of all
         or  a  portion   of  an  issue  of   publicly   or   privately
         distributed  debt  obligations  in accordance  with the Fund's
         investment  objective,  policies and  restrictions,  shall not
         constitute the making of a loan.

Nonfundamental Investment Restrictions
         The  Board  of  Trustees  has  adopted  the  following   nonfundamental
investment  restrictions.   A  nonfundamental   investment  restriction  can  be
changed by the Board at any time without a shareholder vote.

         (1)  The  Fund  may  not   enter   into   reverse   repurchase
         agreements   if  the  aggregate   proceeds  from   outstanding
         reverse   repurchase   agreements,   when   added   to   other
         outstanding  borrowings  permitted  by  the  1940  Act,  would
         exceed 33 1/3% of the Fund's total  assets.  The Fund does not
         intend  to make  any  purchases  of  securities  if  borrowing
         exceeds 5% of total assets.
         (2) The Fund may not invest,  in the aggregate,  more than 15%
         of its net  assets in  illiquid  securities.  The Fund may buy
         and sell  securities  outside the U.S. that are not registered
         with the SEC or marketable in the US.
         (3) The Fund may not invest in securities  of U.S.  issuers if
         more  than 5% of the  value  of  Fund's  net  assets  would be
         invested in such  securities,  excluding  Special Equities and
         High Social Impact Investments.
         (4) The Fund may not make short sales of securities or
         purchase any securities on margin except as provided with
         respect to options, futures contracts and options on future
         contracts.
         (5) The Fund may not enter into a futures contract or an
         option on a futures contract if the aggregate initial
         margins and premiums required to establish these positions
         would exceed 5% of the Fund's net assets.
         (6) The Fund may not purchase a put or call option on a
         security (including a straddle or spread) if the value of
         that option premium, when aggregated with the premiums on
         all other options on securities held by the Fund, would
         exceed 5% of the Fund's total assets.
         (7) The Fund may not write, purchase or sell puts, calls or
         combinations thereof except that the Fund may (a) write
         exchange-traded covered call options on portfolio securities
         and enter into closing purchase transactions with respect to
         such options, and the Fund may write exchange-traded covered
         call options on foreign currencies and secured put options
         on securities and foreign currencies and write covered call
         and secured put options on securities and foreign currencies
         traded over the counter, and enter into closing purchase
         transactions with respect to such options, and (b) purchase
         exchange-traded call options and put options and purchase
         call and put options traded over the counter, provided that
         the premiums on all outstanding call and put options do not
         exceed 5% of its total assets, and enter into closing sale
         transaction with respect to such options.
         (8) The Fund may, under normal circumstances, from time to
         time, have more than 25% of its assets invested in any major
         industrial or developed country which in the view of the
         Subadvisor poses no unique investment risk. The Subadvisor
         considers an investment in a given foreign country to have
         "no unique investment risk" if the Fund's investment in that
         country is not disproportionate to the relative size of the
         country's market versus the Morgan Stanley Capital
         International Europe-Far East-Asia (EFEA) or World Index or
         other comparable index, and if the capital markets in that
         country are mature, and of sufficient liquidity and depth.
         (9) The Fund will invest at least 65% of its assets in the
         securities of issuers in no less than three countries,
         excluding the US, under normal circumstances.
         (10) The Fund may invest up to 30% of its net assets in
         developing countries, which involve exposure to economic
         structures that are generally less diverse and mature than
         in the United States, and to political systems which may be
         less stable. A country is considered a developing country if
         it is not included in the Morgan Stanley Capital
         International World Index.

         Any  investment  restriction  which  involves a maximum  percentage  of
securities  or assets shall not be  considered  to be violated  unless an excess
over the  applicable  percentage  occurs  immediately  after an  acquisition  of
securities or utilization of assets and results therefrom.


- --------------------------------------------------------------------------------
         As noted above,  the  shareholders of the Fund are currently  voting on
various  changes  to the Fund,  pursuant  to a proxy  statement  mailed in early
January,  1999.  These are the  fundamental  investment  restrictions  in effect
until  February  24,  1999,  or which may be in effect if the above  changes are
not approved by shareholders:

Fundamental Investment Restrictions
The foregoing investment objective and the following investment restrictions
may not be changed without the consent of the holders of a majority of
outstanding shares of the Portfolio. A majority of the shares means the lesser
of (i) 67% of the shares represented at a meeting at which more than 50% of
the outstanding shares are represented or (ii) more than 50% of the
outstanding shares.

The Fund may not:
         1.       With   respect  to  75%  of  its   assets,   purchase
         securities  of any  issuer  (other  than  obligations  of,  or
         guaranteed by, the United States  Government,  its agencies or
         instrumentalities)  if,  as a  result,  more  than  5% of  the
         value of its total assets would be invested in  securities  of
         that issuer.
         2.       Concentrate  25% or more of the  value of its  assets
         in any one  industry;  provided,  however,  that  there  is no
         limitation  with respect to investments in obligations  issued
         or  guaranteed   by  the  United  States   Government  or  its
         agencies  and  instrumentalities,  and  repurchase  agreements
         secured thereby.
         3.       Purchase  more  than  10% of the  outstanding  voting
         securities of any issuer.
         4.       Make loans other than  through the  purchase of money
         market  instruments  and  repurchase   agreements  or  by  the
         purchase of bonds,  debentures or other debt  securities.  The
         purchase  by the  Fund  of all or a  portion  of an  issue  of
         publicly  or  privately   distributed   debt   obligations  in
         accordance  with  its  investment   objective,   policies  and
         restrictions, shall not constitute the making of a loan.
         5.       Underwrite the  securities of other  issuers,  except
         to the extent that in connection  with the  disposition of its
         portfolio  securities,  the  Fund  may  be  deemed  to  be  an
         underwriter.
         6.       Purchase  from or sell to any of the Fund's  officers
         or Directors,  or firms of which any of them are members,  any
         securities  (other than capital  stock of the Fund),  but such
         persons  or  firms  may  act  as  brokers  for  the  Fund  for
         customary commissions.
         7.       Borrow  money,  except  from banks for  temporary  or
         emergency  purposes  and then  only in an  amount up to 10% of
         the  value of the  Fund's  total  assets;  provided,  however,
         that outstanding  borrowings  permitted by this section do not
         exceed  33  1/3% of the  Fund's  total  assets.  In  order  to
         secure any permitted  borrowings under this section,  the Fund
         may pledge, mortgage or hypothecate its assets.
         8.       Make  short  sales  of  securities  or  purchase  any
         securities  on margin  except  that the Fund may  obtain  such
         short-term  credits as may be necessary  for the  clearance of
         purchases and sales of  securities.  The deposit or payment by
         the Fund of initial or maintenance  margin in connection  with
         financial  futures  contracts or related options  transactions
         is not considered the purchase of a security on margin.
         9.       Write,  purchase or sell puts,  calls or combinations
         thereof  except  that the Fund may (a)  write  exchange-traded
         covered call options on  portfolio  securities  and enter into
         closing  purchase  transactions  with respect to such options,
         and the Fund may write  exchange-traded  covered  call options
         on foreign  currencies  and secured put options on  securities
         and  foreign  currencies  and write  covered  call and secured
         put options on securities and foreign  currencies  traded over
         the  counter,  and enter into  closing  purchase  transactions
         with respect to such  options,  (b)  purchase  exchange-traded
         call  options  and  put  options  and  purchase  call  and put
         options  traded over the counter,  provided  that the premiums
         on all  outstanding  call and put  options do not exceed 5% of
         its total  assets,  and enter into  closing  sale  transaction
         with  respect to such  options,  and (c)  engage in  financial
         futures contracts and related options  transactions,  provided
         that the sum of the  initial  margin  deposits  on the  Fund's
         existing  futures  and  related  options   positions  and  the
         premiums  paid for related  options would not exceed 5% of its
         total assets.
         10.      Invest  for the  purpose  of  exercising  control  or
         management of another issuer.
         11.      Invest   in    commodities,    commodities    futures
         contracts,   or  real  estate,   although  it  may  invest  in
         securities  which are  secured by real  estate or real  estate
         mortgages  and  securities  of issuers which invest or deal in
         commodities,  commodity  futures,  real  estate or real estate
         mortgages  and  provided  that it may  purchase  or sell stock
         index  futures,   foreign  currency  futures,   interest  rate
         futures and options thereon.
         12.      The  Fund  may   invest   in  the   shares  of  other
         investment  companies  as  permitted  by the 1940 Act or other
         applicable   law;  or  in  connection   with  a   nonqualified
         deferred   compensation   plan   adopted   by  the   Board  of
         Directors,  as long as there  is no  duplication  of  advisory
         fees.

- --------------------------------------------------------------------------------
                          INVESTMENT SELECTION PROCESS
- --------------------------------------------------------------------------------

         Investments  in the Fund are selected on the basis of their  ability to
contribute  to the dual  objective  of the Fund.  The  Subadvisor  uses its best
efforts to select  investments  for the Fund that satisfy the Fund's  investment
and social  criteria  to the  greatest  practical  extent.  The  Subadvisor  has
developed a number of techniques for  evaluating  the  performance of issuers in
each of these areas.  The primary sources of information  are reports  published
by the issuers  themselves,  the reports of public agencies,  and the reports of
groups  which  monitor   performance  in  particular  areas.  These  sources  of
information   are  sometimes   augmented  with  direct   interviews  or  written
questionnaires  addressed  to the  issuers.  It should be  recognized,  however,
that there are few generally  accepted  measures by which  achievement  in these
areas can be readily  distinguished;  therefore,  the  development  of  suitable
measurement  techniques  is largely  within the  discretion  and judgment of the
Advisors of the Fund.
         Candidates  for  inclusion in any  particular  class of assets are then
examined  according  to the  social  criteria.  The  Subadvisor  classifies  the
issuers into three categories of suitability  under the social criteria.  In the
first category are those issuers which exhibit unusual  positive  accomplishment
with respect to some of the  criteria and do not fail to meet minimum  standards
with  respect  to the  remaining  criteria.  To the  greatest  extent  possible,
investment  selections  are made from this  group.  In the second  category  are
those  issuers  which meet  minimum  standards  with respect to all the criteria
but do not exhibit  outstanding  accomplishment  with respect to any  criterion.
This  category  includes  issuers  which  may  lack  an  affirmative  record  of
accomplishment  in these  areas but which  are not  known by the  Subadvisor  to
violate  any of the  social  criteria.  The  third  category  under  the  social
criteria  consists of issuers which flagrantly  violate,  or have violated,  one
or more of those  values,  for example,  a company which  repeatedly  engages in
unfair labor practices.  The Fund will not knowingly  purchase the securities of
issuers in this third category.
         It should be noted that the Fund's  social  criteria  tend to limit the
availability  of  investment  opportunities  more than is  customary  with other
investment  companies.  The Advisors of the Fund,  however,  believe that within
the first and second  categories there are sufficient  investment  opportunities
to permit  full  investment  among  issuers  which  satisfy  the  Fund's  social
investment objective.

- --------------------------------------------------------------------------------
                      DIVIDENDS, DISTRIBUTIONS, AND TAXES
- --------------------------------------------------------------------------------

         The Fund intends to qualify as  regulated  investment  companies  under
Subchapter M of the  Internal  Revenue  Code.  If for any reason the Fund should
fail to qualify,  it would be taxed as a corporation  at the Fund level,  rather
than passing through its income and gains to shareholders.
         Distributions  of realized  net capital  gains,  if any,  are  normally
paid  once a  year;  however,  the  Fund  does  not  intend  to  make  any  such
distributions  unless available capital loss carryovers,  if any, have been used
or have expired.  As of September 30, 1998, the Fund had tax-loss  carryforwards
of $0.
         Generally,   dividends   (including   short-term   capital  gains)  and
distributions  are  taxable  to the  shareholder  in the  year  they  are  paid.
However,  any dividends and  distributions  paid in January but declared  during
the prior three months are taxable in the year declared.
         The Fund is required to withhold 31% of any  reportable  dividends  and
long-term   capital  gain   distributions   paid  and  31%  reportable  of  each
redemption  transaction  occurring in the Balanced,  Equity and Bond  Portfolios
if:  (a)  the   shareholder's   social   security   number  or  other   taxpayer
identification  number ("TIN") is not provided or an obviously  incorrect TIN is
provided;  (b) the shareholder  does not certify under penalties of perjury that
the TIN provided is the  shareholder's  correct TIN and that the  shareholder is
not subject to backup  withholding  under section  3406(a)(1)(C) of the Internal
Revenue   Code   because  of   underreporting   (however,   failure  to  provide
certification  as to the application of section  3406(a)(1)(C)  will result only
in backup  withholding  on dividends,  not on  redemptions);  or (c) the Fund is
notified  by  the  Internal  Revenue  Service  that  the  TIN  provided  by  the
shareholder  is incorrect or that there has been  underreporting  of interest or
dividends by the shareholder.  Affected  shareholders will receive statements at
least annually specifying the amount withheld.
         In  addition,  the Fund is required to report to the  Internal  Revenue
Service the following  information  with respect to each redemption  transaction
occurring in the Fund:(a) the shareholder's  name,  address,  account number and
taxpayer  identification  number; (b) the total dollar value of the redemptions;
and (c) the Fund's identifying CUSIP number.
         Certain  shareholders are, however,  exempt from the backup withholding
and broker reporting  requirements.  Exempt shareholders include:  corporations;
financial institutions;  tax-exempt organizations;  individual retirement plans;
the U.S.,  a State,  the  District of  Columbia,  a U.S.  possession,  a foreign
government,  an  international  organization,   or  any  political  subdivision,
agency or instrumentality of any of the foregoing;  U.S. registered  commodities
or securities  dealers;  real estate investment  trusts;  registered  investment
companies;  bank common trust funds; certain charitable trusts;  foreign central
banks of issue.  Non-resident  aliens,  certain foreign partnerships and foreign
corporations  are  generally not subject to either  requirement  but may instead
be subject to withholding  under  sections 1441 or 1442 of the Internal  Revenue
Code.  Shareholders  claiming  exemption  from  backup  withholding  and  broker
reporting should call or write the Fund for further information.
         Many  states do not tax the  portion of the Fund's  dividends  which is
derived  from  interest  on  U.S.  Government  obligations.   State  law  varies
considerably   concerning  the  tax  status  of  dividends   derived  from  U.S.
Government  obligations.  Accordingly,  shareholders  should  consult  their tax
advisors  about the tax status of dividends and  distributions  from the Fund in
their respective jurisdictions.
         Dividends  paid by the Fund may be eligible for the dividends  received
deduction  available  to corporate  taxpayers.  Information  concerning  the tax
status of dividends and distributions and the amount of dividends  withheld,  if
any, is mailed annually to Fund shareholders.
         Investors  should  note  that  they  may be  required  to  exclude  the
initial sales  charge,  if any, paid on the purchase of Fund shares from the tax
basis of those  shares  if the  shares  are  exchanged  for  shares  of  another
Calvert  Group Fund within 90 days of purchase.  This  requirement  applies only
to the extent that the  payment of the  original  sales  charge on the shares of
the Fund  causes a  reduction  in the  sales  charge  otherwise  payable  on the
shares of the Calvert  Group Fund  acquired in the  exchange,  and investors may
treat sales charges  excluded from the basis of the original  shares as incurred
to acquire the new shares.

- --------------------------------------------------------------------------------
                                NET ASSET VALUE
- --------------------------------------------------------------------------------

         The public  offering  price of the shares of the Fund is the respective
net asset  value per share  (plus,  for  Class A shares,  the  applicable  sales
charge).  The net asset values  fluctuates based on the respective  market value
of the  Fund's  investments.  The net asset  value  per share for each  class is
determined  every  business  day as of the close of the  regular  session of the
New York Stock  Exchange  (normally  4:00 p.m.  Eastern  time) and at such other
times as may be  necessary  or  appropriate.  The Fund  does not  determine  net
asset  value on certain  national  holidays  or other days on which the New York
Stock Exchange is closed:  New Year's Day,  Martin Luther King Day,  Presidents'
Day, Good Friday,  Memorial Day,  Independence Day, Labor Day, Thanksgiving Day,
and  Christmas  Day.  The  Fund's  net asset  value per share is  determined  by
dividing  total  net  assets  (the  value  of its  assets  net  of  liabilities,
including  accrued  expenses and fees) by the number of shares  outstanding  for
that class.
         The  assets  of the Fund are  valued as  follows:  (a)  securities  for
which  market  quotations  are readily  available  are valued at the most recent
closing  price,  mean  between  bid and  asked  price,  or yield  equivalent  as
obtained  from one or more market  makers for such  securities;  (b)  securities
maturing  within  60 days may be valued  at cost,  plus or minus  any  amortized
discount or premium,  unless the Board of Directors  determines  such method not
to be  appropriate  under the  circumstances;  and (c) all other  securities and
assets for which  market  quotations  are not readily  available  will be fairly
valued  by the  Advisor  in good  faith  under the  supervision  of the Board of
Directors.  Securities  primarily  traded on foreign  securities  exchanges  are
generally valued at the preceding  closing values on their respective  exchanges
where  primarily  traded.  Equity  options  are  valued at the last  sale  price
unless  the bid  price is higher or the  asked  price is lower,  in which  event
such bid or asked  price is used.  Exchange  traded  fixed  income  options  are
valued at the last sale price  unless  there is no sale  price,  in which  event
current  prices  provided  by market  makers  are used.  Over-the-counter  fixed
income options are valued based upon current  prices  provided by market makers.
Financial  futures are valued at the settlement  price  established  each day by
the board of trade or  exchange  on which they are  traded.  Because of the need
to obtain  prices as of the close of  trading on  various  exchanges  throughout
the world,  the  calculation  of the Fund's net asset  value does not take place
for  contemporaneously  with the  determination of the prices of U.S.  portfolio
securities.  For  purposes  of  determining  the net asset  value all assets and
liabilities  initially  expressed in foreign  currency  values will be converted
into  United  States  dollar  values  at the mean  between  the bid and  offered
quotations of such  currencies  against  United States dollars at last quoted by
any  recognized  dealer.  If an  event  were to  occur  after  the  value  of an
investment  was so  established  but  before  the net asset  value per share was
determined which was likely to materially  change the net asset value,  then the
instrument  would be valued using fair value  consideration  by the Directors or
their delegates.

- --------------------------------------------------------------------------------
                          CALCULATION OF TOTAL RETURN
- --------------------------------------------------------------------------------

         The Fund may  advertise  "total  return."  Total  return is  calculated
separately  for each  class.  Total  return  differs  from  yield in that  yield
figures  measure  only the income  component  of the Fund's  investments,  while
total  return  includes  not only the  effect of income  dividends  but also any
change in net asset  value,  or  principal  amount,  during the  stated  period.
Total  return is computed by taking the total  number of shares  purchased  by a
hypothetical  $1,000  investment  after  deducting any applicable  sales charge,
adding  all  additional  shares  purchased  within the  period  with  reinvested
dividends and  distributions,  calculating  the value of those shares at the end
of the period,  and dividing the result by the initial  $1,000  investment.  For
periods of more than one year,  the  cumulative  total  return is then  adjusted
for the number of years,  taking compounding into account,  to calculate average
annual total return during that period.
         Total return is computed according to the following formula:

                                P(1 + T)n = ERV

where P = a  hypothetical  initial  payment of  $1,000;  T = total  return;  n =
number  of  years;  and ERV = the  ending  redeemable  value  of a  hypothetical
$1,000 payment made at the beginning of the period.

                       PURCHASE AND REDEMPTION OF SHARES
- --------------------------------------------------------------------------------

                  Investments   in  the  Fund   made  by  mail,   bank  wire  or
electronic  funds  transfer,  or through  the  Fund's  branch  offices,  Calvert
Distributors,  Inc., or other brokers  participating in the distribution of Fund
shares,  are credited to a  shareholder's  account at the public  offering price
which  is the net  asset  value  next  determined  after  receipt  by the  Fund,
Calvert  Distributors,  Inc., or the Fund's custodian bank or lockbox  facility,
plus the applicable sales charge as set forth in the Fund's Prospectus.
         All  purchases  of the Fund shares will be  confirmed  and  credited to
shareholder  accounts  in full and  fractional  shares  (rounded  to the nearest
1/1000th of a share).  Share  certificates  will not be issued unless  requested
in  writing  by the  investor.  No  charge  will be made for  share  certificate
requests.  No certificates  will be issued for fractional  shares. A service fee
of  $10.00,  plus any costs  incurred  by the Fund,  will be  charged  investors
whose purchase checks are returned for insufficient funds.
         The  Fund  reserves  the  right  to  modify  the  telephone  redemption
privilege.
         Amounts  redeemed by  telephone  may be mailed by check to the investor
to the address of record.  Amounts of more than $50 and less than  $300,000  may
be transferred  electronically  at no charge to the investor.  Amounts of $l,000
or more will be transmitted  by wire by the Fund to the investor's  account at a
domestic  bank or savings  association  that is a member of the Federal  Reserve
System or to a  correspondent  bank. A charge of $5 is imposed on wire transfers
of  less  than  $1,000.  If the  institution  is not a  Federal  Reserve  System
member,   failure  of  immediate   notification  to  that   institution  by  the
correspondent  bank  could  result  in a delay  in  crediting  the  funds to the
investor's account at the institution.
         Redemption  proceeds are normally paid in cash.  However,  the Fund has
the right to redeem  shares in assets  other  than cash for  redemption  amounts
exceeding,  in any 90-day  period,  $250,000 or 1% of the net asset value of the
Fund, whichever is less.
         The  right  of  redemption  may be  suspended  or the  date of  payment
postponed  for any period  during  which the New York Stock  Exchange  is closed
(other than  customary  weekend and holiday  closings),  when trading on the New
York Stock  Exchange is  restricted,  or an emergency  exists,  as determined by
the  Commission,  or if the  Commission  has ordered such a  suspension  for the
protection of shareholders.

Commission  ("SEC")  has  entered an order  against  him  relating to his former
service as a director of Community  Bankers  Mutual Fund,  Inc. This fund is not
connected  with any Calvert Fund or the Calvert  Group and ceased  operations in
September,  1994.  Mr.  Guffey  consented  to the  entry  of the  order  without
admitting  or denying the  findings in the order.  The order  contains  findings
(1) that the  Community  Bankers  Mutual  Fund's  prospectus  and  statement  of
additional  information  were  materially  false  and  misleading  because  they
misstated  or failed to state  material  facts  concerning  the  pricing of fund
shares and the  percentage of illiquid  securities  in the fund's  portfolio and
that Mr.  Guffey,  as a member of the fund's  board,  should have known of these
misstatements  and therefore  violated the  Securities Act of 1933; (2) that the
price of the fund's  shares  sold to the public was not based on the current net
asset value of the shares,  in violation of the  Investment  Company Act of 1940
(the "Investment  Company Act");  and (3) that the board of the fund,  including
Mr.  Guffey,  violated the  Investment  Company Act by directing the filing of a
materially  false  registration  statement.  The order  directed  Mr.  Guffey to
cease and desist  from  committing  or causing  future  violations  and to pay a
civil  penalty  of  $5,000.  The SEC  placed  no  restrictions  on Mr.  Guffey's
continuing  to serve as a Trustee or Director of mutual  funds.  DOB:  05/15/48.

         Messrs.  Guffey  and  Silby  serve on the  Fund's  High  Social  Impact
Investments  Committee  which assists the Fund in identifying,  evaluating,  and

         During  fiscal  1998,  Directors  of the Fund not  affiliated  with the

         Directors  of the  Fund not  affiliated  with the  Fund's  Advisor  may
elect to defer  receipt of all or a percentage  of their fees and invest them in
any  fund  in  the  Calvert  Family  of  Funds  through  the  Trustees  Deferred
Compensation  Plan (shown as "Pension or Retirement  Benefits Accrued as part of
Fund  Expenses,"  below).  Deferral  of the fees is  designed  to  maintain  the
parties  in the same  position  as if the fees  were  paid on a  current  basis.
Management  believes  this will have a negligible  effect on the Fund's  assets,
liabilities, net assets, and net income per share.

                       INVESTMENT ADVISOR AND SUBADVISOR
- --------------------------------------------------------------------------------

         The Fund's  Investment  Advisor is Calvert  Asset  Management  Company,
Inc., 4550 Montgomery Avenue, 1000N,  Bethesda,  Maryland 20814, a subsidiary of
Calvert  Group Ltd.,  which is a  subsidiary  of Acacia  Mutual  Life  Insurance
Company of Washington,  D.C.  ("Acacia  Mutual").  Effective January
1, 1999,  Acacia  Mutual merged with and became a  subsidiary  of  Ameritas
Acacia  Mutual  Holding  Company.  Under  the  Advisory  Contract,  the  Advisor
provides  investment advice to the Fund and oversees its day-to-day  operations,
subject to direction and control by the Fund's Board of  Directors.  The Advisor
provides  the Funds  with  investment  supervision  and  management,  and office
space;  furnishes  executive  and other  personnel  to the  Funds;  and pays the
salaries  and fees of all  Trustees/Directors  who are  employees of the Advisor
or its  affiliates.  The  Fund  pays  all  other  administrative  and  operating
expenses,  including:  custodial,  registrar,  dividend  disbursing and transfer
agency  fees;   administrative   service  fees;  federal  and  state  securities
registration fees; salaries,  fees and expenses of trustees,  executive officers
and  employees  of the Fund,  who are not  employees  of the  Advisor  or of its
affiliates;  insurance  premiums;  trade association dues; legal and audit fees;
interest,  taxes and other  business  fees;  expenses  of  printing  and mailing
reports,  notices,  prospectuses,  and proxy  material to  shareholders;  annual
shareholders'  meeting  expenses;  and  brokerage  commissions  and other  costs
associated with the purchase and sale of portfolio securities.
         For its  services,  the  Advisor  receives an annual fee of .75% of the
Fund's  average  daily net  assets up to $250  million,  0.675% of the next $250
million,  and  0.65% on  assets  in excess  of $500  million.  The  Advisor  may
voluntarily defer its fees or assume expenses of the Fund.

Subadvisor
         Murray  Johnstone  International,  Ltd.,  is controlled by United Asset
Management  Company.  For its services to  International  Equity,  it receives a
subadvisory  fee,  paid by the  Advisor,  of 0.45% of the assets it manages  for
International  Equity.  Murray  Johnstone  also  receives a 0.05%  fee,  paid by
CAMCO (not the Fund) for its assistance with the distribution of the Fund.

         The Fund has  received  an  exemptive  order  from the  Securities  and
Exchange  Commission  to  permit  the Fund  and the  Advisor  to enter  into and
materially  amend  the  Investment  Subadvisory  Agreement  without  shareholder
approval.  If approved  then within 90 days of the hiring of any  Subadvisor  or
the   implementation   of  any  proposed   material  change  in  the  Investment
Subadvisory  Agreement,  the Fund  will  furnish  its  shareholders  information
about the new  Subadvisor  or  Investment  Subadvisory  Agreement  that would be
included  in a proxy  statement.  Such  information  will  include any change in
such  disclosure  caused by the  addition of a new  Subadvisor  or any  proposed
material  change in the Investment  Subadvisory  Agreement of the Fund. The Fund
will  meet  this  condition  by  providing  shareholders,  within 90 days of the
hiring of the Subadvisor or  implementation  of any material change to the terms
of an Investment  Subadvisory  Agreement,  with an information statement to this
effect.
         The  advisory  fees  paid to the  Advisor  by the Fund  for the  fiscal
years ended  September 30, 1996,  1997,  and 1998 were  $1,971,329,  $2,134,708,
and $2,338,864, respectively.

         Calvert  Administrative  Services Company ("CASC"), an affiliate of the
Advisor,  has  been  retained  by the  Fund to  provide  certain  administrative
services  necessary to the conduct of its affairs,  including the preparation of
regulatory filings and shareholder  reports.  For providing such services,  CASC
receives an annual  administrative  service fee payable monthly (as a percentage
of net  assets) as  follows  (with a minimum  annual  fee of $40,000  across all
classes):

                                       Class A, B, and C      Class I
         International Equity               0.35%             0.15%

         For fiscal  years  1996,  1997,  and 1998,  International  Equity  paid
$197,133,  $213,471,  and  $233,886,  respectively,  to CASC  in  administrative
fees.  For those  Funds with  multiple  classes,  investment  advisory  fees are

Service fees are allocated as a class-level expense, based on net assets.

                             METHOD OF DISTRIBUTION
- --------------------------------------------------------------------------------

         Calvert Distributors, Inc. ("CDI") is the principal underwriter and
distributor for the Fund. Under the terms of its underwriting agreement with
the Funds, CDI markets and distributes the Fund's shares and is responsible
for preparing advertising and sales literature, and printing and mailing
prospectuses to prospective investors.
         Pursuant to Rule 12b-1 under the Investment Company Act of 1940, the
Fund has adopted Distribution Plans (the "Plans") which permit the Fund to pay
certain expenses associated with the distribution and servicing of its shares.
Such expenses for Class A shares may not exceed, on an annual basis, 0.35% of
the Fund's respective average daily net assets. Expenses under the Fund's
Class B and Class C Plans may not exceed, on an annual basis, 1.00% of the
Fund's Class B and Class C average daily net assets, respectively.
         The Class A Distribution Plans reimburses CDI only for expenses it
incurs, while the Class B and C Distribution Plans compensate CDI at a set
rate regardless of CDI's expenses.
         The  Fund's   Distribution   Plans  were   approved  by  the  Board  of
Directors,  including  the  Directors  who are not  "interested  persons" of the
Fund (as that term is defined  in the  Investment  Company  Act of 1940) and who
have no direct or indirect  financial  interest in the operation of the Plans or
in any  agreements  related to the Plans.  The selection  and  nomination of the
Directors  who are not  interested  persons  of the  Fund  is  committed  to the
discretion of such  disinterested  Directors.  In  establishing  the Plans,  the
Directors  considered  various factors  including the amount of the distribution
expenses.  The Directors  determined that there is a reasonable  likelihood that
the Plans will benefit the Fund and its shareholders.
         The  Plans  may  be   terminated   by  vote  of  a   majority   of  the
non-interested  Directors who have no direct or indirect  financial  interest in
the Plans,  or by vote of a majority of the  outstanding  shares of the affected
class  of  the  Fund.  If  the  Fund  should  ever  switch  to a  new  principal
underwriter  without  terminating  the Class B Plan,  the fee would be  prorated
between  CDI and the new  principal  underwriter.  Any  change in the Plans that
would materially  increase the distribution  cost to the Fund requires  approval
of the shareholders of the affected class;  otherwise,  the Plans may be amended
by the  Directors,  including  a majority  of the  non-interested  Directors  as
described  above.  The Plans will  continue  in effect for  successive  one-year
terms provided that such  continuance is  specifically  approved by (i) the vote
of a majority of the  Directors  who are not parties to the Plans or  interested
persons  of any  such  party  and  who  have no  direct  or  indirect  financial
interest in the Plans,  and (ii) the vote of a majority  of the entire  Board of
Directors.
         Apart from the Plans, the Advisor and CDI, at their own expense, may
incur costs and pay expenses associated with the distribution of shares of the
Fund.
         CDI,  makes a continuous  offering of the Fund's  securities on a "best
efforts"  basis.  Under the terms of the agreement,  CDI is entitled to receive,
pursuant to the  Distribution  Plans, a distribution  fee and a service fee from
the  Fund  based  on the  average  daily  net  assets  of  each  of  the  Fund's
respective  Classes.  These fees are paid  pursuant  to the Fund's  Distribution
Plan.  The  Distribution  Plan Expenses  (includes  both  distribution  fees and
services  fees) paid by the Fund (all  classes) to CDI for the fiscal year ended
September 30, 1998, was $652,432.

         Of  the   distribution   expenses   paid  by  Class  A  Shares  of  the
International  Equity Fund in fiscal year 1998,  $453,021 was used to compensate
dealers for their share  distribution  promotional  services.  $109,123 was used
for the printing and mailing of  prospectuses  and sales  materials to investors
(other  than  current  shareholders),   and  the  remainder  partially  financed
advertising.
         Of  the   distribution   expenses   paid  by  Class  B  Shares  of  the
International  Equity  Fund in fiscal year 1998,  $2,016 was used for  financing
advertising.
         Of  the   distribution   expenses   paid  by  Class  C  Shares  of  the
International  Equity Fund in fiscal year 1998,  $16,318 was used for  financing
advertising.

         Fund  Directors  and certain other  affiliated  persons of the Fund are
exempt  from the sales  charge  since the  distribution  costs  are  minimal  to
persons already  familiar with the Fund.  Other groups (e.g.,  group  retirement
plans) are exempt due to  economies of scale in  distribution.  See Exhibit A to
the Prospectus.

                             PORTFOLIO TRANSACTIONS
- --------------------------------------------------------------------------------

         Fund  transactions  are  undertaken on the basis of their  desirability
from  an  investment  standpoint.   The  Fund's  Advisor  and  Subadvisors  make
investment  decisions  and the choice of brokers and dealers under the direction
and supervision of the Fund's Board of Directors.
         Broker-dealers  who  execute  transactions  on  behalf  of the Fund are
selected  on the  basis of their  execution  capability  and  trading  expertise
considering,  among other factors,  the overall  reasonableness of the brokerage
commissions,   current  market  conditions,   size  and  timing  of  the  order,
difficulty of execution, per share price, etc.

         For the last three fiscal years,  total brokerage  commissions paid are
as follows:

                                    1996             1997           1998
         International Equity       $1,155,171       $749,050       $947,291

        The Fund did not pay any brokerage  commissions  to affiliated  persons
        during the last three fiscal years.

         While the Fund's Advisor select brokers primarily on the basis of best 
execution, in some cases the Advisor may direct transactions to brokers based
on the quality and amount of the research and research-related services which 
the brokers provide to them. These services are of the type described in 
Section 28(e) of the Securities Exchange Act of 1934 and may include analyses 
of the business or prospects of a company, industry or economic sector, or 
statistical and pricing services.

          If, in the judgment of the Advisor, the Fund or other accounts
managed by them will be benefited by supplemental research services, they are
authorized to pay brokerage commissions to a broker furnishing such services 
which are in excess of commissions which another broker may have charged for 
effecting the same transaction. These research services include advice, either
directly or through publications or writings, as to the value of securities, 
the advisability of investing in, purchasing or selling securities, and the 
availability of securities or purchasers or sellers of securities; furnishing 
of analyses and reports concerning issuers, securities or industries; providing
information on economic factors and trends; assisting in determining portfoli
strategy; providing computer software used in security analyses; providing 
portfolio performance evaluation and technical market analyses; and providing 
other services relevant to the investment decision making process. It is the 
policy of the Advisor that such research services will be used for the benefit
of the Fund as well as other Calvert Group funds and managed accounts.

          If, in the judgment of the Advisor, the Fund or other accounts
managed by them will be benefited by supplemental research services, they are
authorized to pay brokerage commissions to a broker furnishing such services 
which are in excess of commissions which another broker may have charged for 
effecting the same transaction. These research services include advice, either
directly or through publications or writings, as to the value of securities,

                              GENERAL INFORMATION
- --------------------------------------------------------------------------------

         The Fund is an  open-end  diversified  management  investment  company,
organized as a Maryland  Corporation on February 14, 1992.  Prior to January 31,
1997, the Fund was known as the Global Equity Fund.
         Each share represents an equal  proportionate  interest with each other
share and is  entitled to such  dividends  and  distributions  out of the income
belonging  to such  class  as  declared  by the  Board.  The  Fund  offers  four
separate  classes of shares:  Class A, Class B, Class C, and Class I. Each class
represents  interests  in the same  portfolio  of  investments  but,  as further
described in the  prospectus,  each class is subject to differing  sales charges
and expenses,  which  differences  will result in differing net asset values and
distributions.  Upon any  liquidation  of the Fund,  shareholders  of each class
are  entitled  to share  pro rata in the net  assets  belonging  to that  series
available for distribution.
         The Fund is not required to hold annual shareholder meetings, but
special meetings may be called for certain purposes such as electing
Directors, changing fundamental policies, or approving a management contract.
As a shareholder, you receive one vote for each share you own, except that
matters affecting classes differently, such as Distribution Plans, will be
voted on separately by the affected class(es).

                                    APPENDIX
- --------------------------------------------------------------------------------

CORPORATE BOND AND COMMERCIAL PAPER RATINGS

Corporate Bonds:
Description of Moody's Investors Service Inc.'s/Standard & Poor's bond ratings:
         Aaa/AAA:  Best  quality.  These  bonds  carry  the  smallest  degree of
investment  risk  and  are  generally  referred  to  as  "gilt  edge."  Interest
payments  are  protected  by a large or by an  exceptionally  stable  margin and
principal is secure.  This rating  indicates an extremely strong capacity to pay
principal and interest.
         Aa/AA:  Bonds rated AA also qualify as high-quality  debt  obligations.
Capacity to pay  principal  and interest is very strong,  and in the majority of
instances,  they  differ from AAA issues  only in small  degree.  They are rated
lower than the best bonds because  margins of protection  may not be as large as
in  Aaa  securities,  fluctuation  of  protective  elements  may  be of  greater
amplitude,  or there may be other elements  present which make  long-term  risks
appear somewhat larger than in Aaa securities.
         A/A:  Upper-medium  grade  obligations.   Factors  giving  security  to
principal  and interest  are  considered  adequate,  but elements may be present
which  make the  bond  somewhat  more  susceptible  to the  adverse  effects  of
circumstances and economic conditions.
         Baa/BBB:  Medium grade obligations;  adequate capacity to pay principal
and interest.  Whereas they normally  exhibit  adequate  protection  parameters,
adverse economic  conditions or changing  circumstances  are more likely to lead
to a  weakened  capacity  to pay  principal  and  interest  for  bonds  in  this
category than for bonds in the A category.
         Ba/BB,  B/B,  Caa/CCC,   Ca/CC:  Debt  rated  in  these  categories  is
regarded as  predominantly  speculative with respect to capacity to pay interest
and  repay  principal.  There may be some  large  uncertainties  and major  risk
exposure  to adverse  conditions.  The higher  the  degree of  speculation,  the
lower the rating.
         C/C: This rating is only for no-interest income bonds.
         D:  Debt  in  default;  payment  of  interest  and/or  principal  is in
arrears.

Commercial Paper:
         MOODY'S INVESTORS SERVICE, INC.:
         The Prime rating is the highest  commercial  paper  rating  assigned by
Moody's.  Among the factors  considered by Moody's in assigning  ratings are the
following:  (1)  evaluation  of the  management  of  the  issuer;  (2)  economic
evaluation  of  the  issuer's   industry  or  industries  and  an  appraisal  of
speculative-type  risks which may be inherent in certain  areas;  (3) evaluation
of the issuer's  products in relation to  competition  and customer  acceptance;
(4) liquidity;  (5) amount and quality of long-term  debt; (6) trend of earnings
over a period of ten years;  (7) financial  strength of a parent company and the
relationships  which exist with the issuer;  and (8)  recognition  by management
of  obligations  which  may be  present  or may  arise  as a  result  of  public
interest  questions and  preparations to meet such  obligations.  Issuers within
this Prime  category may be given ratings 1, 2, or 3,  depending on the relative
strengths of these factors.

         STANDARD & POOR'S CORPORATION:
         Commercial  paper  rated A by  Standard  &  Poor's  has  the  following
characteristics:  (i) liquidity  ratios are adequate to meet cash  requirements;
(ii)  long-term  senior  debt  rating  should be A or better,  although  in some
cases BBB credits may be allowed if other  factors  outweigh the BBB;  (iii) the
issuer  should have  access to at least two  additional  channels of  borrowing;
(iv) basic  earnings and cash flow should have an upward  trend with  allowances
made for unusual  circumstances;  and (v) typically the issuer's industry should
be well  established  and the issuer  should have a strong  position  within its
industry and the reliability and quality of management  should be  unquestioned.
Issuers  rated A are further  referred to by use of numbers 1, 2 and 3 to denote
the relative strength within this highest classification.

                                LETTER OF INTENT

Bethesda, MD 20814

Ladies and Gentlemen:

         By signing this Letter of Intent,  or affirmatively  marking the Letter
of Intent  option on my Fund  Account  Application  Form, I agree to be bound by
the terms and  conditions  applicable  to  Letters  of Intent  appearing  in the
Prospectus  and the  Statement of  Additional  Information  for the Fund and the
provisions  described  below as they  may be  amended  from  time to time by the
Fund. Such amendments will apply automatically to existing Letters of Intent.

         I intend to invest in the shares of:__________(Fund or Portfolio name)
during the thirteen (13) month period from the date of my
first purchase pursuant to this Letter (which cannot be more than ninety (90)
days prior to the date of this Letter or my Fund Account Application Form,
whichever is applicable), an aggregate amount (excluding any reinvestments of
distributions) of at least fifty thousand dollars ($50,000) which, together
with my current holdings of the Fund (at public offering price on date of this
Letter or my Fund Account Application Form, whichever is applicable), will
equal or exceed the amount checked below:

         __ $50,000 __ $100,000 __ $250,000 __ $500,000 __ $1,000,000

         Subject  to the  conditions  specified  below,  including  the terms of
escrow,  to which I hereby  agree,  each  purchase  occurring  after the date of
this Letter will be made at the public  offering  price  applicable  to a single
transaction  of the dollar amount  specified  above,  as described in the Fund's
prospectus.  "Fund"  in  this  Letter  of  Intent  shall  refer  to the  Fund or
Portfolio,  as the case may be.  No  portion  of the  sales  charge  imposed  on
purchases made prior to the date of this Letter will be refunded.

         I am making no  commitment  to  purchase  shares,  but if my  purchases
within  thirteen  months from the date of my first purchase do not aggregate the
minimum  amount  specified  above,  I will  pay the  increased  amount  of sales
charges  prescribed in the terms of escrow  described  below. I understand  that
4.75% of the minimum  dollar  amount  specified  above will be held in escrow in
the form of shares  (computed to the nearest  full share).  These shares will be
held subject to the terms of escrow described below.

         From the initial  purchase  (or  subsequent  purchases  if  necessary),
4.75% of the dollar  amount  specified in this Letter shall be held in escrow in
shares of the Fund by the Fund's  transfer  agent.  For example,  if the minimum
amount  specified  under  the  Letter is  $50,000,  the  escrow  shall be shares
valued in the amount of $2,375  (computed at the public  offering price adjusted
for a $50,000  purchase).  All dividends and any capital gains  distribution  on
the escrowed shares will be credited to my account.

         If  the  total  minimum  investment   specified  under  the  Letter  is
completed  within a thirteen  month  period,  escrowed  shares  will be promptly
released  to  me.  However,  shares  disposed  of  prior  to  completion  of the
purchase  requirement  under  the  Letter  will  be  deducted  from  the  amount
required to complete the investment commitment.

         Upon  expiration of this Letter,  the total  purchases  pursuant to the
Letter  are  less  than the  amount  specified  in the  Letter  as the  intended
aggregate  purchases,  Calvert  Distributors,  Inc.  ("CDI") will bill me for an
amount  equal to the  difference  between  the lower  load I paid and the dollar
amount of sales  charges  which I would have paid if the total amount  purchased
had been  made at a single  time.  If not paid by the  investor  within 20 days,
CDI will debit the difference from my account.  Full shares,  if any,  remaining
in  escrow  after the  aforementioned  adjustment  will be  released  and,  upon
request, remitted to me.

         I irrevocably  constitute and appoint CDI as my attorney-in-fact,  with
full power of  substitution,  to surrender  for  redemption  any or all escrowed
shares on the books of the Fund.  This  power of  attorney  is  coupled  with an
interest.

         The commission  allowed by CDI to the broker-dealer  named herein shall
be at the  rate  applicable  to the  minimum  amount  of my  specified  intended
purchases.

         The  Letter  may  be  revised  upward  by me at  any  time  during  the
thirteen-month  period,  and such a revision  will be  treated as a new  Letter,
except that the  thirteen-month  period  during which the purchase  must be made
will remain  unchanged and there will be no  retroactive  reduction of the sales
charges paid on prior purchases.

         In  determining  the total amount of purchases made  hereunder,  shares
disposed  of  prior  to  termination  of  this  Letter  will  be  deducted.   My
broker-dealer  shall  refer to this  Letter  of  Intent in  placing  any  future
purchase orders for me while this Letter is in effect.

                         INVESTMENT POLICIES AND RISKS
- --------------------------------------------------------------------------------

Foreign Securities
         Investments  in foreign  securities  may  present  risks not  typically
involved in  domestic  investments.  The Fund may  purchase  foreign  securities
directly,  on foreign  markets,  or those  represented  by  American  Depositary
Receipts   ("ADRs"),   or  other  receipts   evidencing   ownership  of  foreign
securities,  such as  International  Depositary  Receipts and Global  Depositary
Receipts.  ADRs are US  dollar-denominated  and traded in the US on exchanges or
over  the  counter.  By  investing  in ADRs  rather  than  directly  in  foreign
issuers'  stock,  the Fund may possibly  avoid some currency and some  liquidity
risks.  The  information  available  for ADRs is subject to the more uniform and
more  exacting  accounting,  auditing and financial  reporting  standards of the
domestic market or exchange on which they are traded.
         Additional  costs may be  incurred  in  connection  with  international
investment  since  foreign   brokerage   commissions  and  the  custodial  costs
associated with maintaining  foreign  portfolio  securities are generally higher
than in the  United  States.  Fee  expense  may  also be  incurred  on  currency
exchanges  when the Fund  changes  investments  from one  country  to another or
converts foreign securities holdings into U.S. dollars.
         United States Government  policies have at times, in the past,  through
imposition of interest  equalization taxes and other  restrictions,  discouraged
certain  investments  abroad by United States  investors.  In addition,  foreign
countries may impose withholding and taxes on dividends and interest.
         Since  investments  in  securities  of  issuers  domiciled  in  foreign
countries  usually involve  currencies of the foreign  countries,  and since the
Fund may temporarily hold funds in foreign  currencies  during the completion of
investment  programs,  the value of the assets of the Fund as measured in United
States  dollars may be affected  favorably or  unfavorably by changes in foreign
currency exchange rates and exchange control  regulations.  For example,  if the
value of the foreign  currency in which a security is  denominated  increases or
declines  in  relation  to the  value  of the  U.S.  dollar,  the  value  of the
security in U.S.  dollars  will  increase or decline  correspondingly.  The Fund
will  conduct  its  foreign  currency  exchange  transactions  either  on a spot
(i.e.,  cash) basis at the spot rate prevailing in the foreign  exchange market,
or  through  entering  into  forward  contracts  to  purchase  or  sell  foreign
currencies.  A forward  foreign  currency  contract  involves an  obligation  to
purchase  or sell a specific  currency  at a future  date which may be any fixed
number of days from the date of the contract  agreed upon by the  parties,  at a
price  set at the  time of the  contract.  These  contracts  are  traded  in the
interbank  market  conducted  directly  between currency traders (usually large,
commercial  banks) and their  customers.  A forward  foreign  currency  contract
generally  has no deposit  requirement,  and no  commissions  are charged at any
stage for trades.
         The Fund may enter into  forward  foreign  currency  contracts  for two
reasons.  First,  the Fund may desire to preserve the United States dollar price
of a security  when it enters  into a  contract  for the  purchase  or sale of a
security  denominated  in a foreign  currency.  The Fund may be able to  protect
itself  against  possible  losses  resulting  from  changes in the  relationship
between  the United  States  dollar  and  foreign  currencies  during the period
between  the  date  the  security  is  purchased  or sold  and the date on which
payment  is made  or  received  by  entering  into a  forward  contract  for the
purchase or sale,  for a fixed  amount of dollars,  of the amount of the foreign
currency involved in the underlying security transactions.
         Second,  when the Advisor or  Subadvisor  believes that the currency of
a  particular  foreign  country  may suffer a  substantial  decline  against the
United States dollar,  the Fund enters into a forward foreign currency  contract
to  sell,  for a fixed  amount  of  dollars,  the  amount  of  foreign  currency
approximating the value of some or all of the Fund's  securities  denominated in
such foreign  currency.  The precise  matching of the forward  foreign  currency
contract  amounts  and the  value of the  Fund's  securities  involved  will not
generally be possible  since the future value of the  securities  will change as
a  consequence  of market  movements  between the date the  forward  contract is
entered into and the date it matures.  The  projection  of  short-term  currency
market  movement is difficult,  and the successful  execution of this short-term
hedging  strategy is uncertain.  Although  forward  foreign  currency  contracts
tend to  minimize  the risk of loss due to a decline  in the value of the hedged
currency,  at the same time they tend to limit any  potential  gain which  might
result should the value of such currency  increase.  The Fund does not intend to
enter  into such  forward  contracts  under  this  circumstance  on a regular or
continuous basis.
         Eurocurrency Conversion Risk. European countries that are members of
the European Monetary Union have agreed to use a common currency unit, the
"euro" , beginning in 1999. Currently, each of these countries has its own
currency unit. Although the Advisor and Subadvisor do not anticipate any
problems in conversion from the old currencies to the euro, there may be
issues involved in settlement, valuation, and numerous other areas that could
impact the Fund. Calvert has been reviewing all of its computer systems for
Eurocurrency conversion compliance. There can be no assurance that there will
be no negative impact on the Fund, however, the Advisor, Subadvisor and
custodian have advised the Fund that they have been actively working on any
necessary changes to their computer systems to prepare for the conversion, and
expect that their systems, and those of their outside service providers, will
be adapted in time for that event.

Temporary defensive positions
         For temporary defensive purposes - which may include a lack of
adequate purchase candidates or an unfavorable market environment - the Fund
may invest in cash or cash equivalents. Cash equivalents include instruments
such as, but not limited to, U.S. government and agency obligations,
certificates of deposit, banker's acceptances, time deposits commercial paper,
short-term corporate debt securities, and repurchase agreements.

Repurchase Agreements
         The  Fund  may  purchase   debt   securities   subject  to   repurchase
agreements,  which are  arrangements  under which the Fund buys a security,  and
the seller  simultaneously  agrees to  repurchase  the  security  at a specified
time and  price  reflecting  a market  rate of  interest.  The Fund  engages  in
repurchase  agreements  in order to earn a higher  rate of return  than it could
earn  simply  by  investing  in  the  obligation  which  is the  subject  of the
repurchase agreement.  Repurchase agreements are not, however,  without risk. In
the  event  of the  bankruptcy  of a  seller  during  the  term of a  repurchase
agreement,  a legal  question  exists as to whether the Fund would be deemed the
owner of the  underlying  security  or would be deemed  only to have a  security
interest  in and  lien  upon  such  security.  The  Fund  will  only  engage  in
repurchase  agreements with recognized  securities  dealers and banks determined
to  present  minimal  credit  risk  by  the  Advisor  under  the  direction  and
supervision  of the Fund's Board of Directors.  In addition,  the Fund will only
engage in repurchase  agreements  reasonably designed to secure fully during the
term of the agreement  the seller's  obligation  to  repurchase  the  underlying
security  and will monitor the market value of the  underlying  security  during
the term of the  agreement.  If the value of the  underlying  security  declines
and is not at least equal to the  repurchase  price due the Fund pursuant to the
agreement,  the Fund will require the seller to pledge additional  securities or
cash to secure  the  seller's  obligations  pursuant  to the  agreement.  If the
seller   defaults  on  its  obligation  to  repurchase  and  the  value  of  the
underlying  security declines,  the Fund may incur a loss and may incur expenses
in  selling  the  underlying  security.  Repurchase  agreements  are  always for
periods  of less than one year.  Repurchase  agreements  not  terminable  within
seven days are considered illiquid.

Reverse Repurchase Agreements
         The Fund may also  engage in  reverse  repurchase  agreements.  Under a
reverse  repurchase   agreement,   the  Fund  sells  securities  to  a  bank  or
securities  dealer and agrees to repurchase  those securities from such party at
an agreed upon date and price  reflecting  a market rate of  interest.  The Fund
invests the proceeds from each reverse  repurchase  agreement in  obligations in
which it is  authorized  to  invest.  The Fund  intends  to enter into a reverse
repurchase  agreement  only  when  the  interest  income  provided  for  in  the
obligation  in which the Fund  invests  the  proceeds  is expected to exceed the
amount the Fund will pay in interest to the other  party to the  agreement  plus
all costs associated with the  transactions.  The Fund does not intend to borrow
for leverage  purposes.  The Fund will only be permitted to pledge assets to the
extent necessary to secure borrowings and reverse repurchase agreements.
         During the time a reverse  repurchase  agreement  is  outstanding,  the
Fund will  maintain in a segregated  custodial  account an amount of cash,  U.S.
Government  securities or other liquid,  high-quality  debt securities  equal in
value to the  repurchase  price.  The Fund  will  mark to  market  the  value of
assets held in the segregated  account,  and will place additional assets in the
account  whenever  the  total  value  of the  account  falls  below  the  amount
required under applicable regulations.
         The Fund's  use of  reverse  repurchase  agreements  involves  the risk
that the other party to the  agreements  could become  subject to  bankruptcy or
liquidation  proceedings  during the period the agreements are  outstanding.  In
such event,  the Fund may not be able to repurchase  the  securities it has sold
to that other party.  Under those  circumstances,  if at the  expiration  of the
agreement  such  securities  are of greater value than the proceeds  obtained by
the Fund  under the  agreements,  the Fund may have been  better  off had it not
entered  into  the  agreement.   However,  the  Fund  will  enter  into  reverse
repurchase  agreements  only with banks and dealers  which the Advisor  believes
present  minimal  credit risks under  guidelines  adopted by the Fund's Board of
Directors. In  addition,  the Fund bears the risk that the  market value of the
securities  it sold may  decline  below the  agreed-upon  repurchase  price,  in
which case the dealer may request the Fund to post additional collateral.

Non-Investment Grade Debt Securities
         Non-investment   grade  debt   securities   are  lower   quality   debt
securities  (generally  those  rated  BB or  lower  by  S&P  or Ba or  lower  by
Moody's,  known  as  "junk  bonds").  These  securities  have  moderate  to poor
protection   of   principal   and  interest   payments   and  have   speculative
characteristics.  (See  Appendix  for  a  description  of  the  ratings.)  These
securities  involve  greater risk of default or price declines due to changes in
the issuer's  creditworthiness than  investment-grade  debt securities.  Because
the market for  lower-rated  securities  may be thinner and less active than for
higher-rated  securities,  there  may  be  market  price  volatility  for  these
securities and limited  liquidity in the resale market.  Market prices for these
securities may decline  significantly in periods of general economic  difficulty
or  rising  interest  rates.  Unrated  debt  securities  may fall into the lower
quality  category.  Unrated  securities  usually are not  attractive  to as many
buyers as rated securities are, which may make them less marketable.
         The quality  limitation  set forth in the Fund's  investment  policy is
determined  immediately  after  the  Fund's  acquisition  of a  given  security.
Accordingly,   any  later  change  in  ratings  will  not  be  considered   when
determining whether an investment complies with the Fund's investment policy.
         When  purchasing  high-yielding  securities,   rated  or  unrated,  the
Advisors  prepare  their own  careful  credit  analysis  to attempt to  identify
those issuers whose financial  condition is adequate to meet future  obligations
or is expected to be adequate in the future.  Through Fund  diversification  and
credit  analysis,  investment  risk can be  reduced,  although  there  can be no
assurance that losses will not occur.

Derivatives
         The Fund  can use  various  techniques  to  increase  or  decrease  its
exposure to changing  security  prices,  interest  rates,  or other factors that
affect security  values.  These techniques may involve  derivative  transactions
such as buying and selling  options and futures  contracts and leveraged  notes,
entering into swap agreements,  and purchasing indexed securities.  The Fund can
use these practices  either as substitution or as protection  against an adverse
move in the Fund to adjust the risk and return  characteristics  of the Fund. If
the Advisor and/or Subadvisor  judges market  conditions  incorrectly or employs
a strategy that does not  correlate  well with a Fund's  investments,  or if the
counterparty to the transaction  does not perform as promised,  these techniques
could result in a loss.  These  techniques may increase the volatility of a Fund
and may involve a small  investment  of cash  relative to the  magnitude  of the
risk assumed. Derivatives are often illiquid.

Options and Futures Contracts
         The Fund may,  in  pursuit  of its  respective  investment  objectives,
purchase  put and call  options  and  engage  in the  writing  of  covered  call
options  and  secured put  options on  securities  which meet the Fund's  social
criteria,  and employ a variety of other  investment  techniques.  Specifically,
the  Fund may also  engage  in the  purchase  and  sale of  stock  index  future
contracts,   foreign   currency   futures   contracts,   interest  rate  futures
contracts, and options on such futures, as described more fully below.
         The Fund may  engage in such  transactions  only to hedge the  existing
positions.  It  will  not  engage  in such  transactions  for  the  purposes  of
speculation or leverage.  Such investment  policies and techniques may involve a
greater  degree of risk than  those  inherent  in more  conservative  investment
approaches.
         Fund may write  "covered  options" on securities in standard  contracts
traded on  national  securities  exchanges.  The Fund may write such  options in
order to receive the  premiums  from  options  that expire and to seek net gains
from closing purchase transactions with respect to such options.

Put and Call Options.  The Fund may purchase put and call  options,  in standard
contracts  traded on national  securities  exchanges,  on  securities of issuers
which meet the Fund's  social  criteria.  The Fund will  purchase  such  options
only to hedge against  changes in the value of securities  the Fund hold and not
for the purposes of speculation  or leverage.  By buying a put, the Fund has the
right to sell the  security at the  exercise  price,  thus  limiting its risk of
loss  through  a  decline  in the  market  value of the  security  until the put
expires.  The  amount  of any  appreciation  in  the  value  of  the  underlying
security  will be  partially  offset by the amount of the  premium  paid for the
put option and any related  transaction  costs.  Prior to its expiration,  a put
option  may be sold in a closing  sale  transaction  and any profit or loss from
the sale will  depend on whether  the amount  received  is more or less than the
premium paid for the put option plus the related transaction costs.
         The Fund  may  purchase  call  options  on  securities  which  they may
intend  to  purchase   and  which  meet  the  Fund's   social   criteria.   Such
transactions  may be  entered  into in order to limit the risk of a  substantial
increase  in the  market  price  of the  security  which  the  Fund  intends  to
purchase.  Prior to its expiration,  a call option may be sold in a closing sale
transaction.  Any  profit or loss from such a sale will  depend on  whether  the
amount  received is more or less than the premium  paid for the call option plus
the related transaction costs.

Covered  Options.  The Fund may write  only  covered  options on equity and debt
securities in standard contracts traded on national securities  exchanges.  This
means that,  in the case of call  options,  so long as the Fund is  obligated as
the writer of a call option,  the Fund will own the underlying  security subject
to the  option  and,  in the case of put  options,  the Fund will,  through  its
custodian,  deposit and maintain  either cash or securities  with a market value
equal to or greater than the exercise price of the option.
         When the  Fund  writes a  covered  call  option,  the  Fund  gives  the
purchaser  the right to purchase  the  security at the call option  price at any
time  during  the life of the  option.  As the  writer of the  option,  the Fund
receives  a  premium,   less  a  commission,   and  in  exchange   foregoes  the
opportunity  to profit  from any  increase in the market  value of the  security
exceeding  the call option price.  The premium  serves to mitigate the effect of
any  depreciation  in the market  value of the  security.  Writing  covered call
options  can  increase  the income of the Fund and thus  reduce  declines in the
net asset  value per share of the Fund if  securities  covered  by such  options
decline  in value.  Exercise  of a call  option by the  purchaser  however  will
cause the Fund to forego future  appreciation  of the securities  covered by the
option.
         When the Fund  writes a covered  put  option,  it will gain a profit in
the  amount  of the  premium,  less a  commission,  so long as the  price of the
underlying  security  remains  above  the  exercise  price.  However,  the  Fund
remains  obligated to purchase  the  underlying  security  from the buyer of the
put  option  (usually  in the event the price of the  security  falls  below the
exercise  price)  at any time  during  the  option  period.  If the price of the
underlying  security  falls  below the  exercise  price,  the Fund may realize a
loss in the amount of the  difference  between the  exercise  price and the sale
price of the security, less the premium received.
         The Fund  may  purchase  securities  which  may be  covered  with  call
options  solely on the basis of  considerations  consistent  with the investment
objectives  and policies of the Fund. The Fund's  turnover may increase  through
the exercise of a call  option;  this will  generally  occur if the market value
of a "covered"  security  increases  and the Fund has not entered into a closing
purchase transaction.
         Risks  Related  to  Options  Transactions.  The Fund can  close out its
respective  positions  in  exchange-traded  options  only on an  exchange  which
provides  a  secondary  market  in such  options.  Although  the Fund  intend to
acquire  and  write  only  such  exchange-traded  options  for  which an  active
secondary  market  appears  to  exist,  there  can be no  assurance  that such a
market will exist for any particular  option  contract at any  particular  time.
This  might  prevent  the Fund from  closing an options  position,  which  could
impair the Fund's  ability to hedge  effectively.  The  inability to close out a
call  position may have an adverse  effect on liquidity  because the Fund may be
required to hold the  securities  underlying the option until the option expires
or is exercised.

Futures  Transactions.  The Fund may purchase and sell  futures  contracts,  but
only when,  in the  judgment  of the  Advisor,  such a position  acts as a hedge
against market changes which would  adversely  affect the securities held by the
Fund.  These  futures  contracts  may  include,  but are not limited to,  market
index  futures  contracts  and  futures  contracts  based  on  U.S.   Government
obligations.
         A futures  contract  is an  agreement  between  two  parties to buy and
sell a  security  on a future  date  which has the  effect of  establishing  the
current  price for the  security.  Although  futures  contracts  by their  terms
require  actual  delivery  and  acceptance  of  securities,  in most  cases  the
contracts  are  closed  out before the  settlement  date  without  the making or
taking of delivery  of  securities.  Upon buying or selling a futures  contract,
the Fund  deposits  initial  margin with its  custodian,  and  thereafter  daily
payments  of  maintenance  margin  are made to and from  the  executing  broker.
Payments  of  maintenance  margin  reflect  changes in the value of the  futures
contract,  with the Fund being  obligated  to make such  payments if its futures
position  becomes less  valuable  and  entitled to receive such  payments if its
positions become more valuable.
         The Fund may only  invest in futures  contracts  to hedge its  existing
investment  positions and not for income  enhancement,  speculation  or leverage
purposes.  Although  some of the  securities  underlying a futures  contract may
not necessarily meet the Fund's social  criteria,  any such hedge position taken
by the Fund will not  constitute a direct  ownership  interest in the underlying
securities.
         Futures   contracts   are   designed  by  boards  of  trade  which  are
designated  "contracts  markets" by the  Commodity  Futures  Trading  Commission
("CFTC").  As series of a registered  investment  company,  the Fund is eligible
for exclusion from the CFTC's  definition of "commodity pool operator,"  meaning
that the  Fund may  invest  in  futures  contracts  under  specified  conditions
without  registering  with  the  CFTC.  Futures  contracts  trade  on  contracts
markets  in a  manner  that is  similar  to the way a  stock  trades  on a stock
exchange  and  the  boards  of  trade,  through  their  clearing   corporations,
guarantee performance of the contracts.

Options  on  Futures  Contracts.  The Fund may  purchase  and  write put or call
options  and sell call  options  on  futures  contracts  in which the Fund could
otherwise  invest  and which are  traded on a U.S.  exchange  or board of trade.
The Fund may also enter into closing  transactions  with respect to such options
to terminate an existing  position;  that is, to sell a put option already owned
and to buy a call option to close a position  where the Fund has already  sold a
corresponding call option.
         The Fund may only  invest in  options  on  futures  contracts  to hedge
their respective existing  investment  positions and not for income enhancement,
speculation or leverage  purposes.  Although some of the  securities  underlying
the futures  contract  underlying the option may not necessarily meet the Fund's
social  criteria,  any such hedge position taken by the Fund will not constitute
a direct ownership interest in the underlying securities.
         An option on a futures  contract  gives the  purchaser  the  right,  in
return for the premium paid, to assume a position in a futures  contract-a  long
position  if the  option  is a call  and a short  position  if the  option  is a
put-at a specified  exercise  price at any time during the period of the option.
The Fund will pay a premium for such options  purchased or sold.  In  connection
with such options  bought or sold,  the Fund will make initial  margin  deposits
and make or receive  maintenance  margin  payments which reflect  changes in the
market  value  of such  options.  This  arrangement  is  similar  to the  margin
arrangements applicable to futures contracts described above.

Put  Options  on  Futures  Contracts.  The  purchase  of put  options on futures
contracts is analogous to the sale of futures  contracts  and is used to protect
the Fund  against  the risk of  declining  prices.  The  Fund may  purchase  put
options and sell put  options on futures  contracts  that are  already  owned by
the Fund.  The Fund will only  engage in the  purchase  of put  options  and the
sale of covered put options on market index futures for hedging purposes.

Call  Options  on  Futures  Contracts.  The  sale of  call  options  on  futures
contracts is analogous to the sale of futures  contracts  and is used to protect
the Fund against the risk of declining  prices.  The purchase of call options on
futures contracts is analogous to the purchase of a futures  contract.  The Fund
may only buy call  options  to close an  existing  position  where  the Fund has
already sold a  corresponding  call option,  or for a cash hedge.  The Fund will
only  engage in the sale of call  options and the  purchase  of call  options to
cover for hedging purposes.

Writing  Call  Options  on Futures  Contracts.  The  writing of call  options on
futures  contracts  constitutes a partial hedge against  declining prices of the
securities  deliverable  upon exercise of the futures  contract.  If the futures
contract price at expiration is below the exercise  price,  the Fund will retain
the full amount of the option  premium  which  provides a partial  hedge against
any decline that may have occurred in the Fund's securities holdings.

Risks of Options and Futures  Contracts.  If the Fund has sold  futures or takes
options  positions to hedge  against  decline in the market and the market later
advances,  the Fund may suffer a loss on the futures  contracts or options which
it  would  not  have  experienced  if it had  not  hedged.  Correlation  is also
imperfect  between  movements in the prices of futures  contracts  and movements
in prices of the securities  which are the subject of the hedge.  Thus the price
of the  futures  contract or option may move more than or less than the price of
the  securities  being hedged.  Where the Fund has sold futures or taken options
positions  to hedge  against  decline in the market,  the market may advance and
the  value  of the  securities  held in the Fund may  decline.  If this  were to
occur,  the Fund might lose money on the futures  contracts  or options and also
experience a decline in the value of its securities.
         The Fund can close out futures  positions  only on an exchange or board
of trade which  provides a secondary  market in such futures.  Although the Fund
intend  to  purchase  or sell only such  futures  for which an active  secondary
market  appears  to exist,  there can be no  assurance  that such a market  will
exist for any particular  futures  contract at any particular  time.  This might
prevent the Fund from closing a futures  position,  which could require the Fund
to make  daily  cash  payments  with  respect  to its  position  in the event of
adverse price movements.
         Options on futures  transactions  bear  several  risks apart from those
inherent  in options  transactions  generally.  The Fund's  ability to close out
its options  positions in futures  contracts  will depend upon whether an active
secondary  market for such options  develops and is in existence at the time the
Fund seek to close its  positions.  There can be no assurance that such a market
will  develop or exist.  Therefore,  the Fund might be required to exercise  the
options to realize any profit.

                            INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------

         Shareholders  of the Fund are  currently  voting on various  changes to
the Fund,  pursuant  to a proxy  statement  mailed in early  January,  1999.  If
approved at the  special  meeting of  shareholders  on February  24,  1999,  the
revised fundamental investment restrictions will be as follows:

Fundamental Investment Restrictions
         The   Fund   has   adopted   the   following   fundamental   investment
restrictions.  These restrictions  cannot be changed without the approval of the
holders of a majority of the outstanding shares of the Fund.

         (1) The Fund may not make  any  investment  inconsistent  with
         its  classification as a diversified  investment company under
         the 1940 Act.
         (2)  The  Fund  may not  concentrate  its  investments  in the
         securities  of issuers  primarily  engaged  in any  particular
         industry  (other than  securities  issued or guaranteed by the
         U.S.  Government  or its  agencies  or  instrumentalities  and
         repurchase agreements secured thereby).
         (3) The  Fund  may  not  issue  senior  securities  or  borrow
         money,  except from banks for temporary or emergency  purposes
         and then  only in an  amount up to 33 1/3% of the value of its
         total  assets or as  permitted  by law and except by  engaging
         in reverse repurchase  agreements,  where allowed. In order to
         secure  any  permitted   borrowings  and  reverse   repurchase
         agreements under this section,  the Fund may pledge,  mortgage
         or hypothecate its assets.
         (4) The  Fund  may not  underwrite  the  securities  of  other
         issuers,  except as allowed  by law or to the extent  that the
         purchase of  obligations  in  accordance  with its  investment
         objective and policies,  either  directly from the issuer,  or
         from  an  underwriter   for  an  issuer,   may  be  deemed  an
         underwriting.
         (5) The Fund may not invest  directly in  commodities  or real
         estate,  although  it  may  invest  in  securities  which  are
         secured  by  real   estate  or  real  estate   mortgages   and
         securities  of issuers  which  invest or deal in  commodities,
         commodity futures, real estate or real estate mortgages.
         (6) The  Fund may not  make  loans,  other  than  through  the
         purchase   of  money   market   instruments   and   repurchase
         agreements  or by the purchase of bonds,  debentures  or other
         debt  securities,  or as permitted by law. The purchase of all
         or  a  portion   of  an  issue  of   publicly   or   privately
         distributed  debt  obligations  in accordance  with the Fund's
         investment  objective,  policies and  restrictions,  shall not
         constitute the making of a loan.

Nonfundamental Investment Restrictions
         The  Board  of  Trustees  has  adopted  the  following   nonfundamental
investment  restrictions.   A  nonfundamental   investment  restriction  can  be
changed by the Board at any time without a shareholder vote.

         (1)  The  Fund  may  not   enter   into   reverse   repurchase
         agreements   if  the  aggregate   proceeds  from   outstanding
         reverse   repurchase   agreements,   when   added   to   other
         outstanding  borrowings  permitted  by  the  1940  Act,  would
         exceed 33 1/3% of the Fund's total  assets.  The Fund does not
         intend  to make  any  purchases  of  securities  if  borrowing
         exceeds 5% of total assets.
         (2) The Fund may not invest,  in the aggregate,  more than 15%
         of its net assets in illiquid securities.
         (3) The Fund may not make short sales of securities or
         purchase any securities on margin except as provided with
         respect to options, futures contracts and options on future
         contracts.
         (4) The Fund may not enter into a futures contract or an
         option on a futures contract if the aggregate initial
         margins and premiums required to establish these positions
         would exceed 5% of the Fund's net assets.
         (5) The Fund may not purchase a put or call option on a
         security (including a straddle or spread) if the value of
         that option premium, when aggregated with the premiums on
         all other options on securities held by the Fund, would
         exceed 5% of the Fund's total assets.
         (6) The Fund may not purchase the obligations of foreign
         issuers if, as a result, such securities would exceed 25% of
         the value of the Fund's assets.
         (7) The Fund may not write, purchase or sell puts, calls or
         combinations thereof except as provided with respect to
         options, futures contracts and options on futures contracts.

         Any  investment  restriction  which  involves a maximum  percentage  of
securities  or assets shall not be  considered  to be violated  unless an excess
over the  applicable  percentage  occurs  immediately  after an  acquisition  of
securities or utilization of assets and results therefrom.


- --------------------------------------------------------------------------------
         As noted above,  the  shareholders of the Fund are currently  voting on
various  changes  to the Fund,  pursuant  to a proxy  statement  mailed in early
January,  1999.  These are the  fundamental  investment  restrictions  in effect
until  February  24,  1999,  or which may be in effect if the above  changes are
not approved by shareholders:

Fundamental Investment Restrictions
         The  Fund has  adopted  the  following  investment  restrictions  which
cannot be changed  without  the  approval  of the  holders of a majority  of the
outstanding  shares of the Fund.  As defined in the  Investment  Company  Act of
1940,  this  means the  lesser of the vote of (a) 67% of the  shares of the Fund
at a meeting  where  more than 50% of the  outstanding  shares  are  present  in
person or by proxy or (b) more than 50% of the  outstanding  shares of the Fund.
The Fund may not:

         1.       With   respect  to  50%  of  its   assets,   purchase
         securities  of any  issuer  (other  than  obligations  of,  or
         guaranteed by, the United States  Government,  its agencies or
         instrumentalities)  if,  as a  result,  more  than  5% of  the
         value of its total assets would be invested in  securities  of
         that  issuer.  (The  remaining  50% of its total assets may be
         invested  without  restriction  except  to  the  extent  other
         investment restrictions may be applicable).
         2.       Concentrate  25% or more of the  value of its  assets
         in any one  industry;  provided,  however,  that  there  is no
         limitation  with respect to investments in obligations  issued
         or  guaranteed   by  the  United  States   Government  or  its
         agencies  and  instrumentalities,  and  repurchase  agreements
         secured thereby.
         3.       Make  loans of more than  one-third  of the assets of
         the Fund,  or as  permitted  by law.  The purchase by the Fund
         of all or a  portion  of an issue  of  publicly  or  privately
         distributed   debt   obligations   in   accordance   with  its
         investment  objective,  policies and  restrictions,  shall not
         constitute the making of a loan.
         4.       Underwrite the  securities of other  issuers,  except
         as  permitted  by the  Board of  Directors  within  applicable
         law,  and except to the  extent  that in  connection  with the
         disposition  of its  portfolio  securities,  the  Fund  may be
         deemed to be an underwriter.
         5.       Purchase  from or sell to any of the Fund's  officers
         or   directors,   or  companies  of  which  any  of  them  are
         directors,  officers or employees,  any securities (other than
         shares of beneficial  interest of the Fund),  but such persons
         or  firms  may act as  brokers  for  the  Fund  for  customary
         commissions.
         6.       Except as required  in  connection  with  permissible
         options,   futures  and  commodity  activities  of  the  Fund,
         invest in commodities,  commodity futures  contracts,  or real
         estate,  although  it  may  invest  in  securities  which  are
         secured  by  real   estate  or  real  estate   mortgages   and
         securities  of issuers  which  invest or deal in  commodities,
         commodity  futures,  real estate or real estate  mortgages and
         provided  that it may  purchase or sell stock  index  futures,
         foreign  currency  futures,  interest rate futures and options
         thereon.
         7.       Invest in the shares of other  investment  companies,
         except as permitted by the 1940 Act or other  applicable  law,
         or pursuant to Calvert's  nonqualified  deferred  compensation
         plan  adopted  by the Board of  Directors  in an amount not to
         exceed 10% or as permitted by law.
         8.       Purchase  more  than  10% of the  outstanding  voting
         securities of any issuer.

- --------------------------------------------------------------------------------
                       PURCHASE AND REDEMPTION OF SHARES
- --------------------------------------------------------------------------------

         Share  certificates  will not be issued unless  requested in writing by
the  investor.  No  charge  will be made  for  share  certificate  requests.  No
certificates will be issued for fractional shares.
         Amounts  redeemed by check  redemption  may be mailed to the  investor.
Certain  Class B and Class C shares  may be  subject  to a  contingent  deferred
sales charge which is subtracted from the redemption  proceeds (see  Prospectus,
"Calculation   of  Contingent   Deferred  Sales  Charges  and  Waiver  of  Sales
Charges").  Amounts of more than $50 and less than  $300,000 may be  transferred
electronically  at no charge to the investor.  Amounts of $1,000 or more will be
transmitted by wire without  charge by the Fund to the  investor's  account at a
domestic  commercial  bank that is a member of the Federal  Reserve System or to
a  correspondent  bank. A charge of $5 is imposed on wire transfers of less than
$1,000.  If the investor's bank is not a Federal Reserve System member,  failure
of immediate  notification to that bank by the  correspondent  bank could result
in a delay in crediting the funds to the investor's bank account.
         Telephone  redemption  requests  which would require the  redemption of
shares  purchased by check or electronic  funds transfer  within the previous 10
business  days may not be  honored.  The Fund  reserves  the right to modify the
telephone redemption privilege.
         New  shareholders  wishing  to  use  the  Fund's  telephone  redemption
procedure  must so indicate on their  Investment  Applications  and, if desired,
designate  a  commercial  bank or  securities  broker and account to receive the
redemption  proceeds.  Existing  shareholders  who at any time desire to arrange
for the  telephone  redemption  procedure,  or to  change  instructions  already
given,  must send a written  notice  to the  Fund,  with a voided  check for the
bank wiring  instructions  to be added. If a voided check does not accompany the
request,  then the request must be signature  guaranteed  by a commercial  bank,
savings  and  loan  association,  trust  company,  member  firm of any  national
securities  exchange,  or certain credit unions.  Further  documentation  may be
required  from  corporations,  fiduciaries,  pension  plans,  and  institutional
investors.
         The Fund's  redemption  check  normally  will be mailed to the investor
on the  next  business  day  following  the date of  receipt  by the Fund of the
written or  telephone  redemption  request.  If the investor so instructs in the
redemption  request,  the check will be mailed or the redemption  proceeds wired
to a  predesignated  account at the  investor's  bank.  Redemption  proceeds are
normally paid in cash.  However,  at the sole  discretion of the Fund,  the Fund
has the  right to  redeem  shares  in  assets  other  than  cash for  redemption
amounts exceeding,  in any 90-day period,  $250,000 or 1% of the net asset value
of the Fund, whichever is less, or as allowed by law.
         The right of  redemption  of Fund shares may be  suspended  or the date
of payment  postponed  for any period  during which the New York Stock  Exchange
is closed (other than customary weekend and holiday  closings),  when trading on
the  New  York  Stock  Exchange  is  restricted,  or  an  emergency  exists,  as
determined by the SEC, or if the  Commission  has ordered such a suspension  for
the  protection  of  shareholders.  Redemption  proceeds are normally  mailed or
wired  the  next  business  day  after a  proper  redemption  request  has  been
received  unless  redemptions  have been  suspended  or  postponed  as described
above.

- --------------------------------------------------------------------------------
                                NET ASSET VALUE
- --------------------------------------------------------------------------------

         The  net  asset  value  per  share  of the  Fund  is  determined  every
business  day as of the close of the New York Stock  Exchange  (generally,  4:00
p.m.,   Eastern  time),  and  at  such  other  times  as  may  be  necessary  or
appropriate.  The Fund does not  determine  net asset value on certain  national
holidays  or other days on which the New York  Stock  Exchange  is  closed:  New
Year's Day,  Martin  Luther King Day,  Presidents'  Day,  Good Friday,  Memorial
Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day.
         The public  offering  price of the Fund's shares is the net asset value
per share (plus,  for Class A shares,  the  applicable  sales  charge).  The net
asset value per share is  computed  separately  for each class by  dividing  the
value of the Fund's total assets,  less its liabilities,  by the total number of
shares  outstanding  for  that  class.  The  Fund's  securities  are  valued  as
follows:  (a) securities for which market  quotations are readily  available are
valued at the most recent  closing price,  mean between bid and asked price,  or
yield   equivalent  as  obtained  from  one  or  more  market  makers  for  such
securities;  (b) securities  maturing within 60 days are valued at cost, plus or
minus  any  amortized  discount  or  premium,  unless  the  Board  of  Directors
determines such method not to be appropriate  under the  circumstances;  and (c)
all other  securities  and assets for which  market  quotations  are not readily
available are fairly  valued by the Advisor in good faith under the  supervision
of the Board of Directors.

Net Asset Value and Offering Price Per Share            As of 9/30/98

         Net asset value per share
         ($75,068,456/2,951,716 shares)                       $25.43

         Offering price per share, Class A                    $26.64

         Class B net asset value and offering price per share
         ($3,310,741/130,978 shares)                          $25.28

         Class C net asset value and offering price per share
         ($6,547,688/265,853 shares)                          $24.63


- --------------------------------------------------------------------------------
                          CALCULATION OF TOTAL RETURN
- --------------------------------------------------------------------------------

         The Fund  may,  from  time to time,  advertise  "total  return."  Total
return is  calculated  separately  for each class.  Total  return  differs  from
yield in that yield  figures  measure  only the income  component  of the Fund's
investments,  while  total  return  includes  not  only  the  effect  of  income
dividends but also any change in net asset value,  or principal  amount,  during
the stated  period.  Total  return is  computed  by taking  the total  number of
shares  purchased by a  hypothetical  $1,000  investment,  after  deducting  the
applicable  sales  charge  for  Class A shares,  adding  all  additional  shares
purchased  within  the  period  with  reinvested  dividends  and  distributions,
calculating  the value of those  shares at the end of the period,  and  dividing
the result by the initial $1,000  investment.  Note:  "Total Return" when quoted
in the  Financial  Highlights  section of the Fund's  Prospectus  and the Annual
Report  to  Shareholders,  however,  per  SEC  instructions,  does  not  reflect
deduction  of the sales  charge,  and  corresponds  to "return  without  maximum
sales load"  return as  referred  to herein.  For periods of more than one year,
the  cumulative  total return is then  adjusted for the number of years,  taking
compounding into account,  to calculate  average annual total return during that
period.
         Total return is computed according to the following formula:

                                P(1 + T)n = ERV

where P = a  hypothetical  initial  payment of $l,000  (less the  maximum  sales
charge imposed during the period  calculated);  T = total return;  n = number of
years; and ERV = the ending  redeemable  value of a hypothetical  $1,000 payment
made at the beginning of the period.
         Performance  is  historical  in nature and is not  intended to indicate
future  performance.  All total return  quotations  reflect the deduction of the
Fund's  maximum  sales charge,  except  quotations  of "return  without  maximum
sales load" (or  "without  CDSC")  which do not reflect  deduction  of the sales
charge.  Return  without  maximum  sales  load,  which will be higher than total
return,  should  be  considered  only  by  investors,  such as  participants  in
certain  pension  plans,  to whom  the  sales  charge  does  not  apply,  or for
purposes of comparison  only with  comparable  figures which also do not reflect
sales charges,  such as Lipper averages.  Thus, in the above formula, for return
without  maximum  sales  load,  P  =  the  entire  $1,000  hypothetical  initial
investment  and does not reflect  deduction of any sales  charge.  Return may be
advertised  for other  periods,  such as by quarter,  or  cumulatively  for more
than one year.


         Return for the Fund's  shares are as  follows,  for the  periods  ended

         Total  return,  like net asset value per share,  fluctuates in response
to changes in market  conditions.  Performance for any particular  period should

         The Fund or its  affiliates  may provide  information  such as, but not
limited   to,  the   economy,   investment   climate,   investment   principles,
sociological  conditions,   and  political  ambiance.   Discussion  may  include

goals.  The Fund may list  portfolio  holdings or give  examples  or  securities
that may have been  considered for inclusion in the  Portfolio,  whether held or

         The Fund or its  affiliates  may supply  comparative  performance  data

cite to any source,  whether in print or on-line,  such as  Bloomberg,  in order
to  acknowledge  origin  of  information.  The Fund may  compare  itself  or its
portfolio holdings to other  investments,  whether or not issued or regulated by

         Calvert Group is the nation's  leading  family of socially  responsible
mutual  funds,  both in terms of socially  responsible  mutual fund assets under
management,  and number of socially  responsible  mutual fund portfolios offered
(source:  Social  Investment Forum,  December 31, 1998).  Calvert Group was also
the first to offer a family of socially responsible mutual fund portfolios.

                      DIVIDENDS, DISTRIBUTIONS, AND TAXES
- --------------------------------------------------------------------------------

         The Fund intends to qualify as  regulated  investment  companies  under
Subchapter M of the  Internal  Revenue  Code.  If for any reason the Fund should
fail to qualify,  it would be taxed as a corporation  at the Fund level,  rather
than passing through its income and gains to shareholders.
         Distributions  of realized  net capital  gains,  if any,  are  normally
paid  once a  year;  however,  the  Fund  does  not  intend  to  make  any  such
distributions  unless available capital loss carryovers,  if any, have been used
or have expired.  As of September 30, 1998, the Fund had tax-loss  carryforwards
of $0.
         Generally,   dividends   (including   short-term   capital  gains)  and
distributions  are  taxable  to the  shareholder  in the  year  they  are  paid.
However,  any dividends and  distributions  paid in January but declared  during
the prior three months are taxable in the year declared.
         The Fund is required to withhold 31% of any  reportable  dividends  and
long-term   capital  gain   distributions   paid  and  31%  reportable  of  each
redemption  transaction  occurring in the Balanced,  Equity and Bond  Portfolios
if:  (a)  the   shareholder's   social   security   number  or  other   taxpayer
identification  number ("TIN") is not provided or an obviously  incorrect TIN is
provided;  (b) the shareholder  does not certify under penalties of perjury that
the TIN provided is the  shareholder's  correct TIN and that the  shareholder is
not subject to backup  withholding  under section  3406(a)(1)(C) of the Internal
Revenue   Code   because  of   underreporting   (however,   failure  to  provide
certification  as to the application of section  3406(a)(1)(C)  will result only
in backup  withholding  on dividends,  not on  redemptions);  or (c) the Fund is
notified  by  the  Internal  Revenue  Service  that  the  TIN  provided  by  the
shareholder  is incorrect or that there has been  underreporting  of interest or
dividends by the shareholder.  Affected  shareholders will receive statements at
least annually specifying the amount withheld.
         In  addition,  the Fund is required to report to the  Internal  Revenue
Service the following  information  with respect to each redemption  transaction
occurring in the Fund:(a) the shareholder's  name,  address,  account number and
taxpayer  identification  number; (b) the total dollar value of the redemptions;
and (c) the Fund's identifying CUSIP number.
         Certain  shareholders are, however,  exempt from the backup withholding
and broker reporting  requirements.  Exempt shareholders include:  corporations;
financial institutions;  tax-exempt organizations;  individual retirement plans;
the U.S.,  a State,  the  District of  Columbia,  a U.S.  possession,  a foreign
government,  an  international  organization,   or  any  political  subdivision,
agency or instrumentality of any of the foregoing;  U.S. registered  commodities
or securities  dealers;  real estate investment  trusts;  registered  investment
companies;  bank common trust funds; certain charitable trusts;  foreign central
banks of issue.  Non-resident  aliens,  certain foreign partnerships and foreign
corporations  are  generally not subject to either  requirement  but may instead
be subject to withholding  under  sections 1441 or 1442 of the Internal  Revenue
Code.  Shareholders  claiming  exemption  from  backup  withholding  and  broker
reporting should call or write the Fund for further information.
         Many  states do not tax the  portion of the Fund's  dividends  which is
derived  from  interest  on  U.S.  Government  obligations.   State  law  varies
considerably   concerning  the  tax  status  of  dividends   derived  from  U.S.
Government  obligations.  Accordingly,  shareholders  should  consult  their tax
advisors  about the tax status of dividends and  distributions  from the Fund in
their respective jurisdictions.
         Dividends  paid by the Fund may be eligible for the dividends  received
deduction  available  to corporate  taxpayers.  Information  concerning  the tax
status of dividends and distributions and the amount of dividends  withheld,  if
any, is mailed annually to Fund shareholders.
         Investors  should  note  that  they  may be  required  to  exclude  the
initial sales  charge,  if any, paid on the purchase of Fund shares from the tax
basis of those  shares  if the  shares  are  exchanged  for  shares  of  another
Calvert  Group Fund within 90 days of purchase.  This  requirement  applies only
to the extent that the  payment of the  original  sales  charge on the shares of
the Fund  causes a  reduction  in the  sales  charge  otherwise  payable  on the
shares of the Calvert  Group Fund  acquired in the  exchange,  and investors may
treat sales charges  excluded from the basis of the original  shares as incurred
to acquire the new shares.

connected  with any Calvert Fund or the Calvert  Group and ceased  operations in
September,  1994.  Mr.  Guffey  consented  to the  entry  of the  order  without
admitting  or denying the  findings in the order.  The order  contains  findings
(1) that the  Community  Bankers  Mutual  Fund's  prospectus  and  statement  of
additional  information  were  materially  false  and  misleading  because  they
misstated  or failed to state  material  facts  concerning  the  pricing of fund
shares and the  percentage of illiquid  securities  in the fund's  portfolio and
that Mr.  Guffey,  as a member of the fund's  board,  should have known of these
misstatements  and therefore  violated the  Securities Act of 1933; (2) that the
price of the fund's  shares  sold to the public was not based on the current net
asset value of the shares,  in violation of the  Investment  Company Act of 1940
(the "Investment  Company Act");  and (3) that the board of the fund,  including
Mr.  Guffey,  violated the  Investment  Company Act by directing the filing of a
materially  false  registration  statement.  The order  directed  Mr.  Guffey to
cease and desist  from  committing  or causing  future  violations  and to pay a
civil  penalty  of  $5,000.  The SEC  placed  no  restrictions  on Mr.  Guffey's
continuing  to serve as a Trustee or Director of mutual  funds.  DOB:  05/15/48.

elect to defer  receipt of all or a percentage  of their fees and invest them in

the same  position  as if the fees  were  paid on a  current  basis.  Management
believes this will have a negligible  effect on the Fund's assets,  liabilities,
net assets, and net income per share.

                               INVESTMENT ADVISOR
- --------------------------------------------------------------------------------

         The Fund's  Investment  Advisor is Calvert  Asset  Management  Company,
Inc., 4550 Montgomery Avenue, 1000N,  Bethesda,  Maryland 20814, a subsidiary of
Calvert  Group Ltd.,  which is a  subsidiary  of Acacia  Mutual  Life  Insurance
Company of Washington,  D.C.  ("Acacia  Mutual").  Effective January
1, 1999,  Acacia  Mutual merged with and became a  subsidiary  of  Ameritas
Acacia  Mutual  Holding  Company.  Under  the  Advisory  Contract,  the  Advisor
provides  investment advice to the Fund and oversees its day-to-day  operations,
subject to direction and control by the Fund's Board of  Directors.  The Advisor
provides  the Funds  with  investment  supervision  and  management,  and office
space;  furnishes  executive  and other  personnel  to the  Funds;  and pays the
salaries  and fees of all  Trustees/Directors  who are  employees of the Advisor
or its  affiliates.  The  Fund  pays  all  other  administrative  and  operating
expenses,  including:  custodial,  registrar,  dividend  disbursing and transfer
agency  fees;   administrative   service  fees;  federal  and  state  securities
registration   fees;   salaries,   fees  and  expenses  of   Trustees/Directors,
executive  officers  and  employees  of the Fund,  who are not  employees of the
Advisor  or of its  affiliates;  insurance  premiums;  trade  association  dues;
legal and audit  fees;  interest,  taxes and other  business  fees;  expenses of
printing  and mailing  reports,  notices,  prospectuses,  and proxy  material to
shareholders;  annual shareholders' meeting expenses;  and brokerage commissions
and other costs associated with the purchase and sale of portfolio securities.
         Under  a  new   advisory   agreement   expected   to  be   approved  by
shareholders  in early 1999,  the Advisor  receives an annual base fee,  payable
monthly,  of 0.65% of the  Fund's  average  daily  net  assets.*  There  were no
expenses reimbursed or fees voluntarily waived.

Subadvisor
         Brown Capital Management, Inc. is controlled by Eddie C. Brown. It
receives a subadvisory fee, paid by the Advisor, of 0.25% of net assets.**

*If the new advisory  agreement  between the Fund and Calvert  Asset  Management
Company,  Inc. is not  approved by  Shareholders,  then the old  agreement  will
continue in effect with the following fees:

         For its  services,  the Advisor  receives  an annual base fee,  payable
monthly,  of 0.80% of the Fund's  average  daily net assets,  with a performance
adjustment to the base fee as follows:

The Equity Portfolio has a performance adjustment to the base fee as follows:

   Performance Relative to S&P 400 Mid-Cap Index     Performance Adjustment
       .10% but less than .25%                                    0.01%
       .25% but less than .40%                                    0.03%
       .40% or more                                               0.05%

   Performance Relative to S&P 500  Performance Adjustment
       .06% but less than .12%                                    0.07%
       .12% but less than .18%                                    0.14%
       .18% or more                                               0.20%

**If  the  new   subadvisory   agreement   for  the  Fund  is  not  approved  by
Shareholders,  the old  agreement  will  continue in effect  with the  following
fees:

         Brown Capital  Management,  Inc.  receives a  subadvisory  fee, paid by
the  Advisor  at a base rate of 0.25% of net asset  plus or minus a  performance
fee adjustment as follows:

   Performance Relative to a Lipper Blended 60%
    Russell Growth Index and 40% Russell 2000 Index  Performance Adjustment
       .10% but less than .25%                                0.02%
       .25% but less than .40%                                0.05%
       .40% or more                                           0.10%

         The Fund has  received  an  exemptive  order  from the  Securities  and
Exchange  Commission  to  permit  it,  pursuant  to  approval  by the  Board  of
Directors/Trustees,  to enter into and materially amend  Investment  Subadvisory
Agreements  without  shareholder  approval.  If approved  then within 90 days of
the hiring of any  Subadvisor  or the  implementation  of any proposed  material
change  in the  Investment  Subadvisory  Agreement,  the Fund will  furnish  its
shareholders  information  about the new  Subadvisor or  Investment  Subadvisory
Agreement that would be included in a proxy  statement.  Such  information  will
include  any  change  in  such  disclosure  caused  by  the  addition  of a  new
Subadvisor  or  any  proposed  material  change  in the  Investment  Subadvisory
Agreement  of  the  Fund.  The  Fund  will  meet  this  condition  by  providing
shareholders,  within 90 days of the hiring of the Subadvisor or  implementation
of any  material  change to the terms of an  Investment  Subadvisory  Agreement,
with an information statement to this effect.
         The  advisory  fees  paid to the  Advisor  by the Fund  for the  fiscal
years ended  September 30, 1996,  1997,  and 1998 were $243,241,  $383,438,  and
$593,353, respectively.
         Calvert  Administrative  Services Company ("CASC"), an affiliate of the
Advisor,  has  been  retained  by the  Fund to  provide  certain  administrative
services  necessary to the conduct of its affairs,  including the preparation of
regulatory filings and shareholder  reports.  For providing such services,  CASC
receives an annual  administrative  service fee payable monthly (as a percentage
of net assets) as follows:

                                       Class A, B, and C      Class I
         Capital Accumulation               0.25%             0.10%

         For fiscal  years  1996,  1997,  and 1998,  Capital  Accumulation  paid
$30,405,  $48,182,  and $74,654,  respectively,  to CASC in administrative fees.
For those Funds with multiple  classes,  investment  advisory fees are allocated
as a Portfolio-level  expense based on net assets.  Administrative  Service fees
are  allocated as a  class-level  expense,  based on net assets.  Prior to 1999,
the  administrative  service  fee for class a, B and C was 10% of average  daily
net assets.

                             METHOD OF DISTRIBUTION
- --------------------------------------------------------------------------------

         Calvert Distributors, Inc. ("CDI") is the principal underwriter and
distributor for the Fund. Under the terms of its underwriting agreement with
the Funds, CDI markets and distributes the Fund's shares and is responsible
for preparing advertising and sales literature, and printing and mailing
prospectuses to prospective investors.
         Pursuant to Rule 12b-1 under the  Investment  Company Act of 1940,  the
Fund has adopted  Distribution  Plans (the  "Plans")  which  permits the Fund to
pay certain  expenses  associated  with the  distribution  of its  shares.  Such
expenses  may not  exceed,  on an  annual  basis,  0.35% of the  Fund's  Class A
average daily net assets.
         Expenses  under the  Fund's  Class B and Class C Plans may not  exceed,
on an annual  basis,  1.00% of the average daily net assets of Class B and Class
C,  respectively.  Class A Distribution Plans reimburse CDI only for expenses it
incurs,  while  the Class B and C  Distribution  Plans  compensate  CDI at a set
rate regardless of CDI's expenses.
         The  Fund's   Distribution   Plans  were   approved  by  the  Board  of
Directors,  including  the  Directors  who are not  "interested  persons" of the
Fund (as that term is defined  in the  Investment  Company  Act of 1940) and who
have no direct or indirect  financial  interest in the operation of the Plans or
in any  agreements  related to the Plans.  The selection  and  nomination of the
Directors  who are not  interested  persons  of the  Fund  is  committed  to the
discretion of such  disinterested  Directors.  In  establishing  the Plans,  the
Directors  considered  various factors  including the amount of the distribution
expenses.  The Directors  determined that there is a reasonable  likelihood that
the Plans will benefit the Fund and its shareholders.
         The  Plans  may  be   terminated   by  vote  of  a   majority   of  the
non-interested  Directors who have no direct or indirect  financial  interest in
the Plans,  or by vote of a majority of the  outstanding  shares of the affected
class or Fund.  If the Fund should ever  switch to a new  principal  underwriter
without  terminating  the Class B Plan,  the fee would be  prorated  between CDI
and  the  new  principal  underwriter.  Any  change  in  the  Plans  that  would
materially  increase the distribution  cost to the Fund requires approval of the
shareholders of the affected class;  otherwise,  the Plans may be amended by the
Directors,  including a majority of the  non-interested  Directors  as described
above.  The  Plans  will  continue  in  effect  for  successive  one-year  terms
provided that such  continuance  is  specifically  approved by (i) the vote of a
majority  of the  Directors  who are not  parties  to the  Plans  or  interested
persons  of any  such  party  and  who  have no  direct  or  indirect  financial
interest in the Plans,  and (ii) the vote of a majority  of the entire  Board of
Directors.
         Apart from the Plans, the Advisor and CDI, at their own expense, may
incur costs and pay expenses associated with the distribution of shares of the
Fund.
         CDI,  makes a continuous  offering of the Fund's  securities on a "best
efforts"  basis.  Under the terms of the agreement,  CDI is entitled to receive,
pursuant to the  Distribution  Plans, a distribution  fee and a service fee from
the Fund  based  on the  average  daily  net  assets  of the  Fund's  respective
Classes.  These fees are paid  pursuant  to the Fund's  Distribution  Plan.  The
Distribution  Plan Expenses  (includes both distribution fees and services fees)
paid by the Fund (all  classes) to CDI for the fiscal year ended  September  30,
1998 was $301,898.

         Of the  distribution  expenses  paid  by  Class  A  Shares  of  Capital
Accumulation in fiscal year 1998,  $144,529,  was used to compensate dealers for
their share  distribution  promotional  services.  $94,893 for the  printing and
mailing of  prospectuses  and sales  materials to investors  (other than current
shareholders), and the remainder partially financed advertising.
         Of the  distribution  expenses  paid by Class B Shares  of the  Capital
Accumulation   Fund  in  fiscal  year  1998,   $6,697  was  used  for  financing
advertising.
         Of the  distribution  expenses  paid by Class C Shares  of the  Capital
Accumulation   Fund  in  fiscal  year  1998,   $5,673  was  used  for  financing
advertising..

         Fund  Trustees  and certain  other  affiliated  persons of the Fund are
exempt  from the sales  charge  since the  distribution  costs  are  minimal  to
persons already  familiar with the Fund.  Other groups (e.g.,  group  retirement
plans) are exempt due to  economies of scale in  distribution.  See Exhibit A to
the Prospectus.

                               FUND TRANSACTIONS
- --------------------------------------------------------------------------------

         Fund  transactions  are  undertaken on the basis of their  desirability
from  an  investment  standpoint.   The  Fund's  Advisor  and  Subadvisors  make
investment  decisions  and the choice of brokers and dealers under the direction
and supervision of the Fund's Board of Directors.
         Broker-dealers  who  execute  Fund  transactions  on behalf of the Fund
are selected on the basis of their  execution  capability and trading  expertise
considering,  among other factors,  the overall  reasonableness of the brokerage
commissions,   current  market  conditions,   size  and  timing  of  the  order,
difficulty of execution, per share price, etc.
         For the last three fiscal years,  total brokerage  commissions paid are
as follows:

                                    1996           1997       1998
         Capital Accumulation       $36,346        $69,826    $103,709

         The Fund did not pay any brokerage  commissions  to affiliated  persons
         during the last three fiscal years.

         While the Fund's Advisor select brokers primarily on the basis of best 
execution, in some cases the Advisor may direct transactions to brokers based
on the quality and amount of the research and research-related services which 
the brokers provide to them. These services are of the type described in 
Section 28(e) of the Securities Exchange Act of 1934 and may include analyses 
of the business or prospects of a company, industry or economic sector, or 
statistical and pricing services.

          If, in the judgment of the Advisor, the Fund or other accounts
managed by them will be benefited by supplemental research services, they are
authorized to pay brokerage commissions to a broker furnishing such services 
which are in excess of commissions which another broker may have charged for 
effecting the same transaction. These research services include advice, either
directly or through publications or writings, as to the value of securities, 
the advisability of investing in, purchasing or selling securities, and the 
availability of securities or purchasers or sellers of securities; furnishing 
of analyses and reports concerning issuers, securities or industries; providing
information on economic factors and trends; assisting in determining portfoli
strategy; providing computer software used in security analyses; providing 
portfolio performance evaluation and technical market analyses; and providing 
other services relevant to the investment decision making process. It is the 
policy of the Advisor that such research services will be used for the benefit
of the Fund as well as other Calvert Group funds and managed accounts.

         For the fiscal year ended  September  30, 1998,  the Fund,  through its
Advisor  and/or  Subadvisor,  directed  brokerage  for research  services in the
following amounts:

                              GENERAL INFORMATION
- --------------------------------------------------------------------------------

         The  Capital  Accumulation  Fund is a series of  Calvert  World  Values
Fund,  Inc.,  an  open-end   non-diversified   management   investment  company,
organized as a Maryland Corporation on February 14, 1992.
         Each share represents an equal  proportionate  interest with each other
share and is  entitled to such  dividends  and  distributions  out of the income
belonging  to such  class  as  declared  by the  Board.  The  Fund  offers  four
separate  classes of shares:  Class A, Class B, Class C, and Class I. Each class
represents  interests  in the same  portfolio  of  investments  but,  as further
described in the  prospectus,  each class is subject to differing  sales charges
and expenses,  which  differences  will result in differing net asset values and
distributions.  Upon any  liquidation  of the Fund,  shareholders  of each class
are  entitled  to share  pro rata in the net  assets  belonging  to that  series
available for distribution.
         The Fund is not  required  to hold  annual  shareholder  meetings,  but
special   meetings  may  be  called  for  certain   purposes  such  as  electing
Directors/Trustees,  changing  fundamental  policies,  or approving a management
contract.  As a  shareholder,  you receive one vote for each share of a Fund you
own. Matters affecting  classes  differently,  such as Distribution  Plans, will
be voted on separately by class.

                                    APPENDIX
- --------------------------------------------------------------------------------

Corporate Bond Ratings:
Description of Moody's Investors Service Inc.'s/Standard & Poor's bond ratings:
         Aaa/AAA:  Best  quality.  These  bonds  carry  the  smallest  degree of
investment  risk  and  are  generally  referred  to  as  "gilt  edge."  Interest
payments  are  protected  by a large or by an  exceptionally  stable  margin and
principal is secure.  This rating  indicates an extremely strong capacity to pay
principal and interest.
         Aa/AA:  Bonds rated AA also qualify as high-quality  debt  obligations.
Capacity to pay  principal  and interest is very strong,  and in the majority of
instances  they  differ  from AAA issues  only in small  degree.  They are rated
lower than the best bonds because  margins of protection  may not be as large as
in  Aaa  securities,  fluctuation  of  protective  elements  may  be of  greater
amplitude,  or there may be other elements  present which make  long-term  risks
appear somewhat larger than in Aaa securities.
         A/A:  Upper-medium  grade  obligations.   Factors  giving  security  to
principal  and interest  are  considered  adequate,  but elements may be present
which  make the  bond  somewhat  more  susceptible  to the  adverse  effects  of
circumstances and economic conditions.
         Baa/BBB:  Medium grade obligations;  adequate capacity to pay principal
and interest.  Whereas they normally  exhibit  adequate  protection  parameters,
adverse economic  conditions or changing  circumstances  are more likely to lead
to a  weakened  capacity  to pay  principal  and  interest  for  bonds  in  this
category than for bonds in higher rated categories.
         Ba/BB,  B/B,  Caa/CCC,   Ca/CC:  Debt  rated  in  these  categories  is
regarded as  predominantly  speculative with respect to capacity to pay interest
and  repay  principal.  The  higher  the  degree of  speculation,  the lower the
rating.   While  such  debt  will  likely  have  some  quality  and   protective
characteristics,  these are  outweighed  by large  uncertainties  or major  risk
exposure to adverse conditions.
         C/C:  This  rating is only for  income  bonds on which no  interest  is
being paid.
         D:  Debt  in  default;  payment  of  interest  and/or  principal  is in
arrears.

Commercial Paper Ratings:
         MOODY'S INVESTORS SERVICE, INC.:
         The Prime rating is the highest  commercial  paper  rating  assigned by
Moody's.  Among the factors  considered by Moody's in assigning  ratings are the
following:  (1)  evaluation  of the  management  of  the  issuer;  (2)  economic
evaluation  of  the  issuer's   industry  or  industries  and  an  appraisal  of
speculative-type  risks which may be inherent in certain  areas;  (3) evaluation
of the issuer's  products in relation to  competition  and customer  acceptance;
(4) liquidity;  (5) amount and quality of long-term  debt; (6) trend of earnings
over a period of ten years;  (7) financial  strength of a parent company and the
relationships  which exist with the issuer;  and (8)  recognition  by management
of  obligations  which  may be  present  or may  arise  as a  result  of  public
interest  questions and  preparations to meet such  obligations.  Issuers within
this Prime  category may be given ratings 1, 2, or 3,  depending on the relative
strengths of these factors.

         STANDARD & POOR'S CORPORATION:
         Commercial  paper  rated A by  Standard  &  Poor's  has  the  following
characteristics:  (i) liquidity  ratios are adequate to meet cash  requirements;
(ii)  long-term  senior  debt  rating  should be A or better,  although  in some
cases BBB credits may be allowed if other  factors  outweigh the BBB;  (iii) the
issuer  should have  access to at least two  additional  channels of  borrowing;
(iv) basic  earnings and cash flow should have an upward  trend with  allowances
made for unusual  circumstances;  and (v) typically the issuer's industry should
be well  established  and the issuer  should have a strong  position  within its
industry and the reliability and quality of management  should be  unquestioned.
Issuers  rated A are further  referred to by use of numbers 1, 2 and 3 to denote
the relative strength within this highest classification.

                                LETTER OF INTENT

Ladies and Gentlemen:

         By signing this Letter of Intent,  or affirmatively  marking the Letter
of Intent  option on my Fund  Account  Application  Form, I agree to be bound by
the terms and  conditions  applicable  to  Letters  of Intent  appearing  in the
Prospectus  and the  Statement of  Additional  Information  for the Fund and the
provisions  described  below as they  may be  amended  from  time to time by the
Fund. Such amendments will apply automatically to existing Letters of Intent.

         I intend to invest in the shares of:                          
(Fund or Portfolio  name)  during the  thirteen  (13) month period from the date
of my first  purchase  pursuant to this Letter (which cannot be more than ninety
(90)  days  prior  to the date of this  Letter  or my Fund  Account  Application
Form,   whichever  is   applicable),   an  aggregate   amount   (excluding   any
reinvestments of  distributions)  of at least fifty thousand  dollars  ($50,000)
which,  together with my current  holdings of the Fund (at public offering price
on  date of this  Letter  or my Fund  Account  Application  Form,  whichever  is
applicable), will equal or exceed the amount checked below:

         __ $50,000 __ $100,000 __ $250,000 __ $500,000 __ $1,000,000

         Subject  to the  conditions  specified  below,  including  the terms of
escrow,  to which I hereby  agree,  each  purchase  occurring  after the date of
this Letter will be made at the public  offering  price  applicable  to a single
transaction  of the dollar amount  specified  above,  as described in the Fund's
prospectus.  "Fund"  in  this  Letter  of  Intent  shall  refer  to the  Fund or
Portfolio,  as the case may be.  No  portion  of the  sales  charge  imposed  on
purchases made prior to the date of this Letter will be refunded.

         I am making no  commitment  to  purchase  shares,  but if my  purchases
within  thirteen  months from the date of my first purchase do not aggregate the
minimum  amount  specified  above,  I will  pay the  increased  amount  of sales
charges  prescribed in the terms of escrow  described  below. I understand  that
4.75% of the minimum  dollar  amount  specified  above will be held in escrow in
the form of shares  (computed to the nearest  full share).  These shares will be
held subject to the terms of escrow described below.

         From the initial  purchase  (or  subsequent  purchases  if  necessary),
4.75% of the dollar  amount  specified in this Letter shall be held in escrow in
shares of the Fund by the Fund's  transfer  agent.  For example,  if the minimum
amount  specified  under  the  Letter is  $50,000,  the  escrow  shall be shares
valued in the amount of $2,375  (computed at the public  offering price adjusted
for a $50,000  purchase).  All dividends and any capital gains  distribution  on
the escrowed shares will be credited to my account.

         If  the  total  minimum  investment   specified  under  the  Letter  is
completed  within a thirteen  month  period,  escrowed  shares  will be promptly
released  to  me.  However,  shares  disposed  of  prior  to  completion  of the
purchase  requirement  under  the  Letter  will  be  deducted  from  the  amount
required to complete the investment commitment.

         Upon  expiration of this Letter,  the total  purchases  pursuant to the
Letter  are  less  than the  amount  specified  in the  Letter  as the  intended
aggregate  purchases,  Calvert  Distributors,  Inc.  ("CDI") will bill me for an
amount  equal to the  difference  between  the lower  load I paid and the dollar
amount of sales  charges  which I would have paid if the total amount  purchased
had been  made at a single  time.  If not paid by the  investor  within 20 days,
CDI will debit the difference from my account.  Full shares,  if any,  remaining
in  escrow  after the  aforementioned  adjustment  will be  released  and,  upon
request, remitted to me.

         I irrevocably  constitute and appoint CDI as my attorney-in-fact,  with
full power of  substitution,  to surrender  for  redemption  any or all escrowed
shares on the books of the Fund.  This  power of  attorney  is  coupled  with an
interest.

         The   commission   allowed  by  Calvert   Distributors,   Inc.  to  the
broker-dealer  named  herein  shall be at the  rate  applicable  to the  minimum
amount of my specified intended purchases.

         The  Letter  may  be  revised  upward  by me at  any  time  during  the
thirteen-month  period,  and such a revision  will be  treated as a new  Letter,
except that the  thirteen-month  period  during which the purchase  must be made
will remain  unchanged and there will be no  retroactive  reduction of the sales
charges paid on prior purchases.

         In  determining  the total amount of purchases made  hereunder,  shares
disposed  of  prior  to  termination  of  this  Letter  will  be  deducted.   My
broker-dealer  shall  refer to this  Letter  of  Intent in  placing  any  future
